Try rebooting your computer , maybe even powering it down and loading up EZB again. Then try it.

I am trying now u think that will work. Thanks for the reply Quick

Did not work tried same error when i try to save what next ...? This is crazy

It should work fine. It does for me. But, when D.J. sees this, he will know what to do. In the mean time hang in there. You might want to post your project if it will let you. I am running windows7 so i can not duplicate the problem.

Even when i try to load someone elses project i get errors.. Cant load and cant save. What a problem.. I have omnibot half completed with arm servos,head, bought robotic arm from dj. All servos work and can be commanded but cant save or load existing program. Wish i could finish this project and have fun with it.

I imagine that D.J. will see this soon. I know how it is to be very anxious. I have not got the gift of patience yet.

Good Luck! Hang in there.

Sounds like you may need to update or reinstall the .net libraries. I've never seen that error before, but it's all I can think of. There are no other reported load/save errors with ARC

Ensure you have the latest updates to windows also. Maybe a library is missing.

thanks dj , i installed on another computer works great... you were right.. first installed computer had corrupt library.. wanted to use windows 7 any way.

since i have your attention.. lol what is best way to drive omnitbot with servos on bottom or existing gear box. if gear box how do you connect to ezb board..

thanks for all your help... i am on my way, will post pics and program of robot when completed..
