Mods don´t work ?

[Pomphis]

Hi, I have recently started with Civ 4. I have downloaded some Mods (Israel, King Solomon, Amazon Civilization, History Rewritten). Israel works. King Solomon works. Amazon Civilization and History Rewritten load, and if I check Advanced - Build they are shown. I also have to unload them. But if I load Amazon Civilization it doesn´t show up when I want to start a game. When I load History Rewritten a normal game starts. Both folders are in their proper place, and I have renamed History Rewritten 0.8 to History Rewritten without effect.

I use the disc, Civ 4 has all updates, OS is Windows XP., also up to date.

Any ideas what the problem might be ?
