Hi!. I need help with 1991 mod names because I installed but I drive with the 2001 names and the 2001 overlays, it has no point to change them in the video game because the performance of the cars are from 2001 season (Schumacher= Senna, Fisichella= Mansell, everything looks like 1991 except the names and the drivers/team performance), the rest of the game is OK, but I need help wih that because it´s impossible to play like that. THANKS!!
Do you use CSM? IF so it sounds like an incomplete restore when you tried to load another mod. Try switching between a few mods (load and unload them in CSM)to see if your problem continues.
If that doesn't work uninstall and then reinstall the mod...

Sounds like the performance file of the mod isn't getting loaded. This has happened to me before with the 79 mod, I think. You can try loading it manually in GPxPatch: disable quickstart in CSM, go to the "GPxSet" tab, enable performance file and search for it.
Not the perfect solution as it requires you doing a bit of work every time you enter the game, but it's a workaround.
