Driod Eris Trackball

I rooted my phone to GUIDE: From stock 1.5 to the latest root 2.1 and after a while the trackball doesn't scroll left.

I tried cleaning it but no good..

Idk if i should unroot it and go to the verzion store and see if they can replace it or just go there with my phone rooted.

I dont think i am using 3rd party rom just updated to new firmware and rooted it


What should i do ????????????
