Hmm, I updated my Rider 2 and didn't lose my favorites. Could it be the map that you have installed? I'm still on 6.67
I didnt lose mine either on my Rider2. But as I said in an earlier post, my "operate my rider" function wouldnt work. It tried downloading the emulator to operate, but always ended in "error". Went back to 7.541 and all is well again.
Cheers
