So i downloaded a .cab on my sprint tp to get all of my wallpapers of every tab. So when i opened it up it looked terrible and wasnt what i wanted. So i then deleted it, and when i now after i reset my machine a few times my touch flo is totally gone and i dont have any of my tabs on teh bottom, no clock or calender button. I do have my bottom and top toolbars.. i tried going through and changing my theme to something else but nothing fixes my problem.. Please Help!
