Peculiar prob with AoM Titans

[DownwardSpyral]

I'm not sure if this is a CRC protection or else something buggy... I install Titans with a backup cd and valid key and update it to 1.01 using the offline updater. It updates fine and then I copy over the 1.01 NoCD from Deviance. I can connect to ESO just fine and browse the games, but when I try connecting to one, it tells me my game is not the same version as the others. I've tried this on many games and attempted to update my version, but its always up to date.
