I found the reason why the religion mod didn't work correctly. The problem is caused by the piece of python code, which looks for the INi files of the ReligionMod and the ReazeCity mod. Maybe its also a problem for the MercenaryMod. This piece of source is is not able to detect the INI file in the mods folder of the installation directory (e.g. c:\program files\sid meiers civilization 4\mods). It would be able to found the INI files in the user directories mod folder (e.g. \own files\my games\sid meiers civilization 4\mods) or in the user directory itself (e.g. \own files\my games\sid meiers civilization 4).
If the INI could not be found, the program usually takes some default values, except for the setting swhere you have to list the religion names in the INI. And the Local Religion setting which is responsible for the Judaism feature is one of them. Because the local religion was not set, the feature was disabled.
This was the reason why I couldn't reproduce the problem, because I still have my INI files in the user directory from the developing phase. after deleting them I had the same problem.
I will work out a fix for that problem this evening or tomorrow. As a hotfix, you can copy the ReligionMod.INI and the RazeCityMod.INI into your user directory (e.g. \own files\my games\sid meiers civilization 4). This should solve the problem immediatly.
Sorry for the difficulties,
