If I go into 'Manage Mods' from the launcher any 3rd party mods in my packages folder are listed as ***Problem Mods***. Mods in question: BMWF1 2008 V1.1RF2 Version 1.0, BMWF1 2008 V1.1RF2 Version 1.2, F12012 LIGUE BETA Version 1.1, F12012 LIGUE BETA Version 1.6. In Single Player - Component Manager there is no option to add anything as suggested in the BMWF1 notes. All RF2 ISI supplied mods and the update are working as expected.
Thanks to LabRat for this: Hi no idea if this will work for u it did for me. Open mod manager click option at the top and take the tick off, now look for car/track and right click on it and click install Sorted
