Anyway, we went into the code for initializing a 4motor robot drive system. and modified it such that it bypassed this error point (removing CAN-Recieve.vi). Then it worked perfectly. So my guess is that you may be able to do something similar in C++.

That a great point... I forgot to ask if the robot was enabled when you got this error. The current image (v19) will not cause a reply if the robot is disabled. This means that, for the moment, you can't call any "Set" commands while the robot is disabled without an error. This will be addressed in the next update. It won't cause any trouble (the way the C++ library is written), but it will create some errors on the DS. As ChristopherBuck noted, in LabVIEW it is written with status chaining so one of these errors will prevent it from working from then on.
