The game is very old and 'Topware', who I believe developed and produced the game is and has been defunct for quite a while. I think, don't really know for sure. This access code you are to get when you register I believe is computer generated from some where and randomly generated. I think but don't know for sure that this server looks for a valid email address and issues the code. The server may also be subject to internet difficulities as well.
I suggest if you are not able to get through after several tries, ask for your refund. It's a shame though because imo, a very good game.
Earth 2160 Keygen Activation Free
The keys on the back of the manual, the game manual i usually keep inside the conveniant plastic DVD case that usually accompanys most games but no not earth 2160, just like World in Conflict i get a freakin cardboard box with cd's and a tiny paper thing to keep them in, bullshit! Both those games look like they had high production values, earth 2160 comes with its own soundtrck CD but they skimp on the physical packaging, crap!
So anyways ive lost the manual, i think it was thrown out with the rest of my game manuals in a big box (manuals from the old jewel case games era) because they were infested with tiny black critters that liked either reading old game manuals or the paper they were made of So i dont have my key, the key i got from a random website didnt work, it wont even let me play single player without a valid key and thats all i wanted to do. This isnt fair! What do i do?
