Did the clean install of TSL with the two patches and no mods work? Kind of need to make sure about that step before troubleshooting the mod installation.
As for the mod maker there isn't a possibility the scripts could have to be recompiled for European versions of the game with the mod installed is there? I made some script changes to my game and found I had to recompile them with TSLRCM installed for them to work once I installed that mod, so apparently script compiling is specific to the game setup as intended for playing (hence mods with a lot of script changes maybe buggy with other mods installed even if there's no specific file incompatability).
Has the mod been tested in Euro versions?
