its started in act 2 in hell when i try to enter dungeon (always at the same spot) diablo crashes and error message 1A5308CF-CEC3-4118-A4CC-4C5405106A60 appears.
i have waited for my party to pass this point and then join them and thats worked, but after a while i get same error when trying to enter another dungeon.
got the game for 6 months and never had problems.
any ideas how to fix it anyone?
