And besides, I can't enter the game, my CD-key is incorrect (why do they need a CD-key for an open beta? <img src="/ubbthreads/images/graemlins/suspicion.gif" alt="" />).
To prevent copies to be leaked ?
What copies? It's an open beta, everyone can get it... And the hackerthing could make sense. But thay can just as easilly get the client too, and they won't need a CD-key in order to get their hands on the exe.files.
