We had a few queries in the mapping forum and so I decided to "fix" the necessary files required to run Geomod.
The complete set of fixed Geomod files can be downloaded here.
It is advisable to extract the files into the mods folder and then work with Geomod there. Once finished (without error or crash) the files can then simply be copied. As always a set of back up files is advisable.
Note: always run the "convert_all" bat file in the data\text folder before copying. You may have to install Python 2.6.8 to run that program.
Edit: Geomod does not work with the 'sieging' entry - you will have to manually add it back to the end of the "Shahan_Shah" character entry (line 9431) in descr_strat
