After clicking on the exit to Vienna the game crashes and says vampire.exe has encountered a problem and needs to close. man am tired of again and again trying to enter Vienna. This crap is freaking my mind out >please somebody help me

One of the most common probs with the game. Luckily, you aren't too far in because you're going to need to start over. Download the Age of Redemption mod and you'll be able to play the whole game, with improved AI and a few other enhancements.
