Can you give more detail? Such as which feature you are using, what's connected to the EZ-B, what the debug window says when it disconnects etc.

any feather i wanna try it disconnects or ARC crach. and i wanted to use just two servo's like auto possition or callibration , or just simpel horizontal servo all crach or disconnects.

i foget to tell you,normal when you open ARC it opens the callibrationpage off you project.that does ARC no more.

sorry about the callibration again.

Have you tried uninstalling ARC then downloading a fresh copy and re-installing it?...

What's connected to the EZ-B? What does the debug window say when it disconnects? Are the servos connected correctly and proven to be working fine?

ARC wont always ask for a servo profile when you open a project. Does the project ask for a fine tuning profile if you open it on a different PC?

Don't you need .NET 4.5 for ARC? Have you checked that?

@feganmeister He has .NET... He already had it working for a long time now, but for some reason today @nomad is having trouble with ARC...
