There's a shortcut to it in the C2C folder, but it should be here:
"\Documents\My Games\Beyond the Sword\Logs\PythonErr.log"
The only important log file for python errors is: PythonErr.log

I will try to copy that file from my old usersetting... these 4 files are not rebuildd when you delete user settings folder, maybe you need to know that screenshot... i manualy copy them now from my old folder.
Thats because old foldername was CustomDomAdv now its DomesticAdv can you upload here what you got in your DomesticAdv folder in usersettings folder?
