Thank you for all of the suggestions! I have tried everything that has been posted, but still no luck haha. Deleted D2 Registry completely (Double checked to make sure it was gone before reinstalling, then tried to manually update the registry.) I also have added DEP exceptions for the launcher, game.exe, and d2.exe just like the tutorial asked. Sometimes the game loves to run, other times it has no desire at all lol. I think my easiest solution may be to just bite the bullet and run a virtual windows xp os, pc should have plenty of juice to do it.
