So I just downloaded SS6.3 and 6.4. The problem I have is after clicking my faction selection for the campaign, it quits back to the main menu. No error, no CTD; it just sends me back to the main menu.
I can run quick and custom battles fine, just not campaign.
If it helps, I'm running Win7 (on which I have the admin account). Med 2 and Kingdoms are installed, and work perfectly; and I've already taken ownership of my medieval 2 directory, but it still doesn't seem to be working. Plus I don't have any submods or anything - just Med2+Kingdoms and now SS6.4
Hopefully someone can help, thanks in advance.
