Your Account is not Authorized to play PA

I bought the game today and activated the key on https://store.uberent.com/account/mykeys but when i sign into the game via the launcher i downloaded from the website it tells me I need to activate the game and when i try it tells me the key was already used. any ideas?

Seems like you using Windows XP, am I right? I got same problem in Virtual Machine with XP inside.
XP is not supported, game won't work on XP, ever.

windows 7 ultimate 64 bit edition

It's quite strange, what is site says about your key?
https://store.uberent.com/account/mykeys
It's your name in "Activated by" column?

Also try to update .Net runtime:

If you converted key to Steam your previous activation been revoked. Now you need to link your Steam account to UberEnt account before you can play game though launcher.

If you run game though Steam it's should be linked automatically when you run game though Steam and login to Uberent in-game once. If it's not working you can always link it manually here:
