ok, so my XP CD Key doesn't work anymore, so I called Microsoft and they're sending me a new copy of XP Pro. Basically, the process requires XP be installed first, like you mentioned, then Win7 after that. I'm not going to reinstall all my stuff just yet, but I did get Combined Ops Installed so I can play something! I have like 20 games I can't play with 7, so this is kind of exciting. Hope it all works out as planned. Woot!
