Calling any experts who might know the answer. Since I bought Diablo 1, every time I try to launch Hellfire, the game closes before it even opens. Diablo itself works perfectly. I contacted Blizzard for help, and they told me everything is fine and the game is running. By the way, I've tried everything: compatibility mode, running as administrator, and even checking the advanced settings, all to no avail. Does anyone have any suggestions or theories, please?
