Vampire Bloodlines. Help

[ph00k]

ok, i've got a really annoying problem where bloodlines just exits to desktop, any ideas? can't find the patch, so its really killing because i really wanna find out what happens next. for details on where it exits to the desktop read below:

spoiler:


it happens after you confront the vampire hunter bach, kill him, talk to the archaeologist, and then a dying bach sets off some remote detonation. you have 1min to get to the boat. i get in the boat with the archaeloghist and the game just exits..... anyone got this prob??

help please !!! :?
