How to change my Tap Tap Revenge 4 avatar?

this is really making me mad ._. i accidentally picked this avatar that looks like it has no eyes and its irritating the crap out of me D8 can i somehow delete the avatar? or change it o.o? i went into retarded mode and uninstalled the app and reinstalled it, but all that did was take away all the songs i worked hard for LOL ^^;
