I purchased a P2 that had been demo'ed and I can't get the software to connect. I have tried on 2 different computers and on both PC's (one W8, one W7) it shows them connected as a device and installs the software, but it never connects to the software. Could it possibly be registered to the other user and that have something to do with it? Any other ideas? I have downloaded the latest version of Assistant. One other thing I have noticed, I click on the link for the plain P2, but the software says Vision, I figured maybe they were the same? I have tried both the remote and the quad and neither will show up in the software.
