Okay, thats sad that you arefacing issues with this controller. Really sorry for you man... Anyways, I assume that you have tried without xbcd and pinnacle also? I mean, with defaut MS drivers... And, what exactly is the problem? The controller is not working at all or what?
Back in 2007 when I bought this controller, I used to use xbcd for every game. Then cam a couple of games (Teenage mutant ninja turtles etc.) that officially supported x360 controller but I did not know that. And the games wont even start with xbcd drivers. As soon as I uninstalled the xbcd drivers, the games were playable with button prompts and all....
So, if you have not tried without xbcd drivers, please do so now. With today's games, you dont need them at all..
