Hello, fellow nerds.

I am currently running Virtual PC 7 on my Mac so that I can run the Poker skins and a bunch of other non-Mac friendly sites. I have purchased a copy of Windows XP but the problem is that I have upgraded my version of Virtual PC a few times and each time I had to reinstall Windows. Now, each time that I reinstall it asks me to register the copy of Windows, so I type in the info and everything is fine. But I guess I finally did it one too may times because it now says that my info is no good anymore. Do I need to buy a brand new copy of Windows....? i hope not. Can i just call them up and tell them what's what? Do they even have phone numbers?

Thanks for any advice.
