I just tried to open my project and I get a Windows error box on the screen saying "Unable to load project. Object reference not set to an instance of an object".
So then I tried to load it from the Cloud and I get the same thing. I have a gazillion hours in my project and I can't imagine it all for not.
Here is a copy of the file. I have restarted my computer and reloaded ARC.
Your file looks corrupted, do you have any backup/ older version of it to try on ?
Hopfully DJ or someone would be able to open an edit it
Looking at the project it seems like you only have the Interface Builder and the Sound Servo. Yet the interface builder shows controlcommands to scripts which are not in the project file...
By removing the sound servo control manually (not with ARC) I can get it to load however all it loads up is the interface builder. Is this correct?
If not, do you have a back up of one with more in it? The save file doesn't contain any EZ-Scripts or any other controls.
But from what I can see in the save all that's there is the interface builder (with all buttons set up to ControlCommand() scripts etc.) and the sound servo. Removing the sound servo from the project will make it open again.
I've attached a "fixed" version of all I can salvage. Again, wait to see if DJ can do more.Junior-635458720809126250-noss.ezb
I keep 2 older versions as backups for all important projects. For instance I have MelvinA, MelvinB and MelvinC. I'll open the latest, say MelvinB, save as Melvin C (which is the oldest of the three) and that way I'll have at least 2 steps backwards in case of problems like this one or in case I accidently delete something I needed.
Hope that works for you.
That is what I had to do.

I am not connected when loading successfully.
1) Are you able to connect to the ezb wifi in ap mode?
2) Are you able to connect to the ezb web server?
3) What lights are on the ezb?
4) Does the ezb chime when powered on?
5) Does the ezb speak and inform you of resetting to default values when the reset button is pressed?
6) Does the ezb chime when an ARC connection is executed?
I can state this enough to ppl who have trouble - but connecting in default AP mode before making any network changes is a good idea. There are many videos on the learn section to help. But it's best to diagnose issues with AP mode before making network changes.
That way, you can let us know if it works in AP mode to rule out a defective ezb
If it works in AP mode, then it's either an issue with your router or network configuration.
i dony know if it would help.i had same problem and aldebaran recomended,
to erase your browser history.and it did help for me.

ones they drop below surten point the connection can dissepear or,
motion dont work.
1) Are you able to connect to the ezb wifi in ap mode? NO
2) Are you able to connect to the ezb web server? NO
3) What lights are on the ezb? Blue
4) Does the ezb chime when powered on? Yes
5) Does the ezb speak and inform you of resetting to default values when the reset button is pressed? Yes
6) Does the ezb chime when an ARC connection is executed? It used too when I had a connection.
This is not an EZ-B issue. The EZ-B works just fine. At the moment it is a connection issue. Once I solve this issue I will get back to my project issues.
Any help on what in the world is going on with my connectivity problem would be greatly appreciated.
1) Do you have virus software or firewall? (Other than the Microsoft firewall)
Another thing to try is to remove the existing ezb wireless configuration from windows. Follow these instructions:
1) click the wireless icon in the system tray near the clock
2) select the menu option at the bottom "network settings and sharing"
3) a new window will open with options along the left. Select Manage Wireless Networks
4) locate any instances of ezb. Select and remove them.
Have you always used that computer or is there another computer that you connected to for the configuration change on the EZB?
With my desktop wired and wireless connections my subnet is 192.168.1.1-255. i was unable to connect too.
but tried on laptop only connect wireless to connect and set my v4. it works fine.
after that able to connect with desktop after v4 was on my subnet.

You never answered the question about what virus scan you are running. There have been several reports that Avast is interfering with EZ-B connections.
Alan
Bookmaker, can you clarify if you are using a Laptop or a Desktop?
If so, can you disconnect the Ethernet cable and try connecting to the EZB?
What alan is stating is that you may have an ip address conflict because your Ethernet and Wireless are both attempting to 192.168.1.x addresses.
Not sure he is, but the symptoms fit an address conflict pretty well. They also fit an overly aggressive firewall or AV app too.
Eventually we'll have a large enough community that EZ-B owners will be able to arrange meetups to help each other out. I would offer to do a screen share, but you need Internet access for that, and in AP mode, you won't have internet access, so that won't help.
That being said (and not meaning to hijack the thread) a web site suggestion: we should be able to share our state or locale in our profile (maybe under our names where we show country now) so that it would be easier for community members to find local help.
I think Bookmaker is in Texas. If he was in the greater DC/Baltimore megalopolis, I would volunteer to meet to help figure this out in person.
Alan
There are many ways to screen share if you have Internet access, but when connecting to an EZ-B in AP mode, you won't have Internet access, so it doesn't matter.

The ARM chip being used on the ezb is not as friendly toward i2c devices as the microchip PIC was. With the ARM, if the i2c is not responsive it will lock up. Silly I know, but that's how it was physically designed by STM Electronics.
That was a challenging one.

I merged my saved project that wasn't loading together with an empty project as mcsdaver said, and then checked all controls except the Sound Servo. Then it worked.
This shouldn't happen though. Its a major bug in the software. Next ARC update please.
