When I load the launcher it will sometimes sit on "Initializing for 60+ seconds", or sometimes it loads quickly to show "Play". Once I click Play I see the Diablo face, then the problem begins. It pretty much sits there indefinitely, though if I go away for 10-15 minutes the game will occasionally load.
Once the game loads (if it does) it runs as well as it always has on this PC. I haven't made any hardware changes of any sort for months, and the game has run fine on this computer as recently as last week.
Any help would be greatly appreciated!
