i was playing angry birds it was on a disk that i bought in a shop and when i was playing it said do you want to update? so i clicked yes then when it downloaded i opened the game and it said Error! attempt to index global 'flurry' (a nil value) (call stack not available) so i desided to delete the game and install it again but me, being a computer noob deleted the game files from program files and %appdata% instead of uninstalling it and now in programs in the control panel it says i have it installed and when i try to uninstall it it says There is a problem with this windows insteller package. A program required for this install could not be run.Contact your support personnel or package vendor. and when i try to install angry birds again it says: A more recent verson of Angry Birds is allredy installed on this computer please help! i love this game.
-PS: i have windows 7
-PPS:i deleded the program files permanlty from the recycle bin
