I think that BW2 blacklists the alcohol/daemon tools driver names. You can try using anti-blaxx (known cure to the problem), or changing your driver names (nor verified yet).
When all else fails just use anti-blaxx. I know, it could messup your computer, but lets forget about the negatives, and look at the positives, you'll have a messed up computer that plays black and white.

P.S. btw, when i say messed up, i mean it screws with the registry, thats why you should use anti-blaxx to "save important data" first, then use it.
