I Purchased GC 2 Ultimate recently and had similar issues loading under Windows 7. The Game would NOT load correctly via the launcher. However, I found that I could open Dread Lords from the ".exe" directly rather than the loader. This is possibly due to a working configuration from a previous install of Dread Lords (only). This didn't work for Dark Avatar or Twilight though. On a hunch, I checked the "Prefs.ini" in all three and found that for the expansions the default values weren't working. After changing the following lines in "Prefs.ini" for both expansions to match those of Dread Lords, all will load from the associated ".exe".
