Okay, so I installed Barbarian Invasion, and patched it up to 1.6. But now I can't play the original imperial RTW campaign! I can load it fine, but after I choose which faction I want to play and click on the button to start, it goes back to the Single Player menu. Has anyone else encountered this? I checked out the Bug threads in the RTW forums and haven't come across anything like this, although I haven't yet read through them all (those are pretty long threads). I tried to install RTW a second time, hoping to put it into a different folder and just play the original from that, but the installer won't let me.
