Well this is a little odd, I updated my rFactor2 the other evening, gave it a quick go, but with life and work I didn't get to play around much. So yesterday I loaded it up fine, all the updates were in place, I did a few races at a couple of tracks, one with rain and one without, and all seemed fine. This afternoon I turned on my P.C. loaded up Steam, went to play rFactor 2, and it said it wasn't installed. So I took a look in installed directory, and it's still there. I go back into Steam, and the only option I have is to install the game. So I choose that, it found it's folder, verified which files I had, and has now presented me with a "Downloading Workshop Items" screen, some 200+ lol. I'm hopeful that at the end of it the sim will work again, but have absolutely no idea as to why it worked last night, and not today ?
