I'm on Windows 8.1 btw. My setup has always worked in the past. Something must have happened recently though ( I don't know what), and it stopped working. Besides reinstalling my OS I don't what what else to try at this point.
I have the same problem. At first I thought it might be the drivers but I tried three different versions and it didn't make a difference. Let me know if you want to IM W1zzard.
