new cg2 controller problems

[manwinder]

wats up guys, i was having a few problems with my new xbox 360 controller(the newest one), i had installed flex rapidfire, and then 1 time the y button stopped working, and then it stopped working to the point where, the controller would be thinking i am pressing the y button when i am not and it would press it like 1000's times(y,y,y,,y,y,y,y,y,y,y), and then my a button and b button got messed up, i can't select anything, if i click a it usually thinks i am click b and b doesn't work sometimes
