I have the same problem as xvaiper7.
i bought the deluxe edition, installed DS2, went fine. completed it.
upgraded to v2.2 along the way, still fine.
installed DS2:BW, went fine.
tried to play DS2:BW, and i got the same error as xvaiper7.
i was really annoyed because i obviously cant complete the story. i looked on forums and couldn't find anyone else with this same problem, so i thought it might be something with the CD, maybe a corrupt file, i dunno. i took the CD to a friends house and installed it there, along with BW, and there it worked fine.
so i came home, formatted my PC, installed all the drivers + software as i always do, and installed DS2:BW, and it worked! yay
but then after some windows updates, it no longer works
here is a screen shot of the next error screen following on from
any help would be greatly appreciated
