Use Darky's keychanger to actually apply the OA Key to your regedit.
I bought a OA key but I cant figure out where to activate it. I am totally clueless, steam doesn't accept the key but darky's key changer said it was valid. Could someone please reply with a quote or pm how to use this key, thanks.
