tartarus V2 won't stop moving down.

Hi All, After a week or two, my thumbpad is moving my toons in a downward movement constantly. I can change directions,  but then it moves downward again. I also can’t use any of the keys, since the downward S is constantly on. I’ve deleted Synapse4 and reinstalled it, deleted all of my profiles,, and cleaned all Razor information from my registry. I then re-installed Synapse 4 and the Colors, with no improvement.  What else can I try?
