I was trying to download bike graphics and rider kits, but then I put rider kits into the wrong folder. Without realising I started the game up and everything was gone including tracks, it gave me tutorial messages like I had never played the game. I deleted everything and tried redownloading the OEM pack, everything is in the bikes and tire folder but when I load the game nothing is there. I also deleted my profile set up, all tracks (didn't have many), rider gear, bike graphic everything so I could just restart, but still no show. All my settings reset too. Could someone help?
