I want to make sure I got this right. I tried uninstalling version 1.0 first but it said I couldn't since it was being used by 4 other mods, so I installed 10.1 and it went right in, but now I seem to have 2 versions of the same track. is that right?
What I did was, before starting rF2, I remove the Fuji track version 1.0 by removing the map 1.0. -> found in [rF2 install map]\installed\locations\Fuji2012\1.0.
This worked for me.
