Okay, I found why my D2 wasn't running - I noticed it runs fine if I close Comodo internet security. Not just battle.net - I am talking just starting the game. Without turning it off, my screen just goes black full screen and dead - needs reboot.

I added game.exe and D II.exe to trusted app etc on the CIS - yet it still happens.

Is there anyway I can play this game with CIS still on? Even when I disable the firewall on it, it still does it - its only when I close CIS - that Diablo 2 runs fine.

Imbaq,

I'd suggest you ask the support people at Comodo.
