Beat: Vista is bad for poker

[jfreels]

So I installed Vista about a month ago to play Shadowrun (fun btw), but I did not look to see how it would affect all my poker programs.

Needless to say Vista is not/was not compatible with most of the programs that I use.
So I reinstalled XP pro. The key apparently does not work anymore and so I need to activate it within the next 2 days. Does anyone know how to do this? I bought Vista but there's no way I'm buying XP now.

Cliff notes: I need to activate XP Pro. How do I do this.
