If you have a legit copy of Windows, you should be able to call up M$ and work it out with them. (I know, not a pleasant thought.) I've been fortunate that my copy validates properly, but I'm really worried about when I reformat my hard-drive and upgrade some of my computer hardware what's going to happen.
@Kieran,
A LOT of legit Windows owners have been screwed over by M$ and their genuine advantage crap. I wouldn't blame him over it. Hopefully, you can work it out by calling Microsoft.
Oh, and yes, you should download CodeSurge when you're able to get DBP up and running again.
Good performance is better than a good excuse.
