What else you can try @D Tom and all the other Guys is not only deleting the "temp" Folder which is adviced previously. To delete this fellow Folder in AppData Folder on your C Drive could sometimes helps too! Follow the path in the screenshots below. "Benutzer" word in the path means just User in german. In the on going path you will see the path ends with a user config File for Mod Manager or even Editor Tool. There are always saved your "old" configs for TU 5 a.e. After deleting the whole Folder, when you next time start FMM, the config File will be renewed with fresh Data. Give it a try when nothing else seems to help. Not a hard requirement just another attempt. So no promises here. But you can delete the Folder or back it up before. Like I mentioned, the FMM builds the Folder again after launching it.
