Just received my GC2A today through Ebay and enjoying the performance app so far. I have noticed that the firmware is out of date though, so I downloaded the updated version to my PC. However, when I try to connect it to the GC2, I get an error (doesn't find the GC2). When I plug the GC2 into the USB, the PC makes the same noise as when I connect my mouse or keyboard, so it is registering but still no luck. Any ideas?
