Can't get into Forsaken world, but it's not what you think!

SO I got a beta key form one of those free beta key websites, and I was accepted. I downloaded the game and all that, but the game says that my user ID/Pass is not correct. I figure the beta key that was accepted wasn't for this patch of Forsaken world, but here's the thing. I got an email from Perfect World accepting me into the current patch, with a different beta key that I can not use. Is there anyway I can switch the two keys so I can play the current patch? HELP!!!
