This is the damndest thing.
First, system specs:
Intel i5 3.something ghZ quad core
nVidia 8800 GTS (640 mb video RAM)
4 gB RAM
Windows 7 SP1
I just upgraded to W7 a couple days ago. DM worked fine on my old XP install, I probably put ~200 hours into it. Now, the launcher will boot Shogun, but as near as I can tell, I'm playing vanilla, at least in campaign mode. The unit multipliers are not applied on the campaign map, but my custom battles can have cards with 800+ men in them--so I'm not sure whether the mod is working or not.
I have already uninstalled DM and verified my game cache through Steam. It found and replaced 11 files, but still no dice with a fresh DM install. I've turned off UAC and run the launcher as an Administrator--nothing. Anyone have any ideas?
