I have a 2010 Macbook Pro, running Lion. My issue lies in one file that really doesn't want to be deleted. I moved some space-hogging games onto my external hard drive to free up space, only to find that it simply copied the .app into the hard drive. No matter, I just sent the local .apps into the trash and attempted to delete. No luck running the empty trash. I deleted items one by one until I was left with the offender .app. It seems to be my sims3.app file. When I try to load it up, i get a message telling me that "You can't open the application The Sims3 because it may be damaged or incomplete," When I do try to empty the trash, it says preparing to empty trash; items to delete: 0 and never loads anywhere, even after being left for hours. If I try to stop the empty, same thing, nothing happens. It just says stopping. I've tried all sorts of sudo commands, but nothing has worked. Can anyone help me out and see what I can do about this pesky file?
