Mad Catz Wired X-Box 360 Controller for Windows HELP!!!?

I have had this controller for 3-4 years, little to no problems... Lately, I've been having problems... Whenever I plug in the controller in Saints Row 2; it takes control of the camera panning feature, and zooms out/above my character! I have tried calibrating, resetting to defaults- and NOTHING works!!! AAARGH! I am thinking on just getting a new controller... Is there hope that I could get my controller to work properly again? Or am I better off buying a new one?

Ps,

I've smacked the controller out of frustration a few times... My counseling doesn't help me, it just pisses me off...
