[amir17901m]

hi 
i installed cod4 (call of duty ) using WINE !

and it worked pretty well ! but when i attempted to uninstall this game from my computer 

i couldn't do it ! the installer says that the game is uninstalled successfully but the game is still there and i can play it when i click on it's icon !!
i appreciate your comments on this !

my distro is  ubuntu 11.04 ;)
