Downloaded App won't open.
I downloaded Civilization V from the App store. However, when I tried to open the app, I received the following message:
“Civilization V: Campaign Edition.app” is damaged and can’t be opened. Delete “Civilization V: Campaign Edition.app” and download it again from the App Store.
I deleted the app and downloaded it again. Same problem. Is there a solution to this problem? (By the way, I downloaded a free app to see if that would open. It did without a problem). Ialso shut down the computer and restarted it... That didn't help.
