i'd suggest u delete the mod files (anything with F1stockcars in the name within the rfactor main folder) and play the game briefly using the default cars and tracks to make sure everything is working, then install V1.0 for the F1s and one track to check they're working, then add v1.1 for the f1s and the other tracks that are available once you're happy that the basic files are ok. Also, make sure you're using version 1.255 of the rfactor game, and i'd recommend you use the full installer. Remember, now you have your activation code for the game (the code you received after buying) you can uninstall rfactor completely and re-install and then activate with your code. (see rfactor homepage downloads for the links)
