When i try to add the Myo (Misc), the ARC crash. I have try 10 times. EZ is started as Admin in Win 10.
Is this in a new, untouched project file, or in an already created file? Try in a new file and see if it works. Otherwise it might be a bug with ARC.
Is Myo armband working correctly ?
Did you follow the instructions:
