USB booting :: Crash after AutoConfig

I'm just starting out on this and have ran into a couple of problems already. I've overcome all but this one, right after autoconfiguring devices it crashes. I checked out my install on another Vista machine and it worked fine. I shutdown everything running on my machine that I possibly can all to no avail. I get this crash dialogue after but I can't make heads nor tails of it.
