@Robinmist if theres nothing wrong with your gamefiles, it could be that some of the FFs in the mod is not being loaded or maybe even corrupted in the place they are in the disk (kinda low chance but ive seen it in the past), and probably the one with most chance of happening is that you have some/alot of custom scripts already in the scripts folder that could be interfering with the mods own scripts. just rename that scripts folder so you dont need to delete them.
