Fallout new vegas CD key problem

[Whoolpurse]

Hey all.
I got myself new Vegas today, and guess what? It says the CD-key is invalid, I've tried countless times, double checked and double checked my double checking, and it goes nowhere.
From what i see on the steam support pages is that my CD-key is apparently one letter/number short. You guys tried this or know the solution?

NVM guys after a few hours i can see that a W was actully two V's.
