I downloaded the new verion of undead live through the app store and it loaded what seemed to be most of it, then the progress bar went back to empty and got stuck there. It has been stuck like that all day now(10 hours) and if I go to iTunes it says it's intalled. I tried restarting the phone with no luck and I can't delete it because there is no x in the corner like all the others, what can I do??
