I've just finished downloading DC from GOG, but I get a hard crash every time I click on training grounds under tutorial, or start under single player->story campaign. Changing graphics setting around didn't fix this, already running as admin (in Windows 7, fully patched), and using imperial version or not didn't change anything. I've run the support tool and all the checks come up fine, and I've emailed support, but I figured someone here might know a fix.
