Yeah, all tracks and cars mode never works for me. I always get errors saying that like mas files are missing. Choosing a car makes my game get stuck. I have to alt tab to desktop. Then I have to click the rfactor tab and the error message pops up. I have to move my mouse pointer straight up to click OK (otherwise my mouse pointer disappears!)
So yeah, I was wondering if this was just a poorly made feature that maybe mod makers said screw it and have not even bothered to make mods to work for?
I've reinstalled rfactor numerous times in the past thinking I screwed something up, but I'm thinking now that maybe it isn't me thats causing the problem because it does this every time and the mods work 100% fine when just used as intended.
