FFH won't load...

That one means it is pretty likely that you only have the patch installed, not the main mod as well.

Make sure you followed all the steps in this guide and it should install properly.

Ok I now have FFH working on my internet PC. What files do I have to copy to get patch 3.13 on my non-internet PC? All of them? Because my memory stick isn't big enough to copy the lot. Why are all the patch files I see empty? It says I have the patch an FFH works but where in the files is the patch exactly? Quick response please.

The patches are installer programs. You run them, and they install the needed files the right place automatically (assuming you installed Civ IV in the default location. This can cause some problems for Vista users.)

Does patch 3.13 change anything in the vanilla civilization 4 folder or just things in the bts folder inside it? Does it change anything in ''My Games'' or just things in '' Program Files''?

Everything installed fine but I need to copy the patch across to my non-internet PC.

EDIT: Problem finally solved. Thanks.
