Windows XP sp3 installed, civ version 1.74, I think I have installed a couple of mods directly into the civ 4 .dll file, mainly the unoffical patch, no other mods. I also have the BAT 1.1 and BUG 3.51 installed for BTS.
I have the original dvd in drive for Civ 4, game loads, HoF mods loads, but asset checker doesn't. Mod notifies me of invalid game for HoF,
Also strangely I can't access the capital city interface either, I just played a game, testing out the options, but it wouldn't give me the interface for the capital, just the map around it.
