FfH Freezes every 30 Seconds

Hey.

I'm running Civ4 version 174 build 1.7.4, and FfH 1.0. I have no expansions, just the original. Every 30 seconds, Civ4 freezes randomly for about 15 seconds. You can do the math, it's not a happy time.

I'm playing as Azktor (Orcish Clans) and it's very early in the game. Size Huge, 6 AIs and myself, on the fantasy realms map. This is my first time with Ffh 1.0. I had FfH version 0.70 and FfH2 0.23 back when I first had Civ4 installed, and it ran fine. Any ideas why it's doing this now? There's no HDD or cd access during the freeze, it just sits there.

Thanks for reading.

P.S. Am I crazy, or is FfH 1.0 almost all new races and no unique units? I remember playing as the Calabim and getting werewolves.

FfH1 uses some placeholder civs and doesnt have any UU's. FfH2 has the Calabim and such in it.
