Any help would be greatly appreciated. Thanks.
I am not sure what could be the cause of that.
Have you tried a fresh install of GTR2 and putting season 16 physics first and skins 2nd rather than just uninstalling the UKGTR stuff? You will of course need to redo ALL game options and settings if you do this.
I have one install of GTR2 that I have setup how I like with GTR2 XD and no CD patch etc but, no other mods or anything. I always copy this when starting a new GTR2 install and leave that one as Vanilla as possible. I recommend doing the same if you have lots of GTR2 installs (like me
). It saves on having to do all in game settings and options every time.
