I purchased the upgrade from Lion to Mountain Lion in the App store.  However, when I try to install Mountain Lion, I get the message "This copy of the install OS X Mountain Lion application can't be verified.  It may be corrupted or tampered with during downloading."  It then says, "Delete this copy of the application, and go to the Purchases page of the Mac App Store to download a new copy."


I've downloaded it a half dozen times (and several, several hours...), I've changed connections, turned off WiFi, everything else.  Not sure what else to do. 


Any suggestions. 

iMac (27-inch Mid 2010), OS X Mountain Lion (10.8.2)
