Huawei ascend, softkeys not working?

I have a cricket huawei ascend and last night i downloaded the buttonremapper app (because my power button wasn't working right). Anyway, it froze my phone and it kept turning off. When I finally got the phone back on, I deleted the app, and now all my softkeys arent working (call, menu, trackball, back, and end call). I can scroll with the trackball but nothing else. Does anybody know what the problem might be or how to fix it?
