Analog sticks on gamepad not working

If you can tell me how to fix my mistake, I'd appreciate it. I was playing FF7 when I got to the first save point. I went to it, and it told me I didn't have any memory cards inserted. So I went to press the F1 button to quicksave, and accidentally hit F5 when I was reaching for my controller again. The controller stopped working. When I hit F5 again to reenable the controller, everything came back BUT the analog controls. They don't work at all. Even after I quit, restarted the program, and restarted FF7, the analog controls would not work. I went back and reconfigured the controller, and it still didn't work. The analog doesn't work at all anymore and the control pad on this thing is for crap and barely functions. >_> Can somebody tell me how to get the analog back? ;_;
