Did you actually purchase a vB license? Because if you did, vBulletin gives you free support. I'm guessing you didn't because you would know this if you actually did buy it. If you did, then go ask the guys over at vBulletin, we can't help you much here.

I'm not being funny but I doubt you dropped a couple of hundred dollars on it, and don't know how to link up the database for it or w/e.
