--- Comment #8 from rmlipman@gmail.com 2012-01-01 23:18:08 CST --- Here's a workaround I found:
Get the SDActivate.exe and SDActivate.lng from an unpatched install from a retail dvd (fresh wineprefix is easiest way).
Sins of a Solar Empire: Replace SDActivate.exe and SDActivate.lng with the old versions
Galactic Civilizations II: Replace SDActivate.exe and SDActivate.lng with the old versions Also replace the same files in the Twilight/ folder
Demigod: Replace ReactorActivate.exe and ReactorActivate.lng with the old versions Make sure to rename the files from SDActivate to ReactorActivate
This should work for other Stardock games, but I have no way to test.
