This is a known problem: cuz your R7 is really outdated against recent R11 - if you only update some of essential parts the result is mostly bad.
You avoid many troubles if you make a sharp cut and new download/install the recent version R11
You must be registered to see the links
After the new install is running well you can transfer your personal stuff (UserData, mods/MyMods) from your R7l, don´t forget some plugins from [Optional] or mods that have a part in abdata.
Keep your old game as backup until the new game is running to your satisfaction.
