I have a new computer (with XP SP3), and I've already registered the game with my previous computer. Now I installed it to the new one, and tried to re-register the game, with no luck. Yes, I've done everything that is said in the faq here. I opened the IE, it has cookies enabled, I cleared all cookies (even when I don't use IE usually), I closed my virus program and the firewall, still I get the message that my validation key is wrong. I just wanted to install the EE to the game, and replay it once again, but this seems to be a difficult thing to do. On my profile here I see the game registered to me. Could anyone please help me?
