I just purchased GalCiv 2: Utlimate Edition from Impulse, downloaded and installed on my Windows 7 64bit machine and went to play. However, the Tutorials button is greyed out, and the Campaigns window has no campaigns.
I searched and found one topic advertising a registry fix, but it's from August of 2009, and I don't know whether that's still a true fix or not for my version. Which, strangely enough, reports as 1.53 in the lower left corner when I load the game, but the Impulse Product Page reports the version as 2.03.
