A pair of students in one of my Robotics classes has problems loading up a previously working JD Profile. I took the JD to my computer and tried loading my JD Profile. After 2 tries, it worked on my PC. I then took JD back to their PC and it worked for my JD Profile after 3 tries. This was yesterday. Today, when they tried to use JD, the profile would not load. I took JD back to my PC and tried. It would not work. Something strange is happening. I just don't know what it could be. I have uploaded the different profiles being used. My profile is "JD-Profile-TayZack." It worked when theirs wouldn't. Now it doesn't work either.

I assume that they are fine but without knowing what to look for exactly (I dont know if the setting are correct) I can only speculate.
I have another JD that I will test on Tuesday to see if I get the same results.
I began creating another default profile for JD, but that made the shoulder setting values get pretty large. I decided to stop since it did not look right. Could there be something wrong with this JD's body or EZ-B?
My students are pretty frustrated with this and asked if they could switch robots. I could see where they were coming from with all this inconsistency, so I assigned them another robot - Roli. Hopefully they will have better luck with Roli.
In the mean time, I will pursue getting to the bottom of the problem with this JD. Any help is much appreciated. Thanks.
1) file incorrectly named
2) servo wires are connected in incorrect spots
A servo profile, in reference to the howto video, should take less than 2 minutes. If the servo profile is "that out of whack", I wonder if the servos are not connected to their proper ports.
I have attached a picture of JD when it connects. As you will notice, the shoulders are horizontal. Since I cannot fine tune the shoulders enough to get them to a vertical state (with what I have worked with thus far), is there something else that I might be able to try?
Remove the arm at the shoulder, turn 90 degrees, and reconnect the clip and play connector.

I do still have problems with consistently connecting to JD and loading its profile. This occurred more often on one of the classroom PCs. On my PC this happens only occasionally. Since the students are now working with Roli, I am not as concerned with the JD problem anymore. The horizontal shoulders was the real worry. I will consider this problem resolved.
