Forgive my assumption. It sounds like you're doing things right.

So now I'm not sure I understand what your robot is doing. Does it work okay until you press Enter? That would certainly disable it, as you should now know.

The "Left and Right Motors" error message means the robot isn't setting the drive motors often enough. If it only happens once when the robot gets disabled, and doesn't repeat continually, it probably isn't going to affect the operation of the robot. But let's keep looking for the cause anyway. Did you change anything in the Disabled vi? The default project sets the drive motors to zero in Disabled. If you removed that, you'll get the error because the motors aren't being set when the robot is disabled.
