I just bought the game off steam and got to playing with it to learn the ropes then went on to try to install the oem factory bikes and messed it up somehow causing the bikes to be invisible, so in turn I uninstalled the game to try to start from scratch by redownloading but now steam is giving me a disk read error, i installed other games to make sure my drives weren't muffed and they install fine so i think i've got some residual files left over from the original installation, if anyone has any tips on how to fix this that'd be great. Love this game as i did with MX sim. Any responses appreciated.
