when i bought a second copy of MTW, I installed it on my computer and gave the old copy to the second computer. But when i try to start a game on the two computers it wont let me play. Right when i join on the other computer it tells me that the latency is to high and goes back to the starting screen of LAN menu.I think this problem is do to that i could not change my CD key on my computer when i installed the new copy of MTW and that the second computer has the same key. help will be appreciated.
