I once had a similar problem with Rome TW. Then I uninstalled AVG Antivirus Free 8.0, and the game ran fine again. I don't know if this is really relevant, but you might want to try uninstalling antivirus software... If you think it's worth the risk, or you don't need to use the internet too often.
Is there anywhere I can download this game? I couldn't run M2TW even if I wanted to.
