it would help if you would give the steps your taking in trying to achieve the end result .If your trying to import a finished tga file into the game , put the tga file into your exports/import folder in the game directory and then start the game then go to the opponent manager for the correct mod and create a new driver then once your get that hit the import button (you have to do it for the car and the pitcrew ) and then find the tga file in the listing for car then you have to do the same thing for the pit crew then once you see them in the opponent manager then hit save and you now have your car and crew in the game then go to the player info option and inside that option choose your player for single and multiplayer for the listing that you wish to race with , you'll need to do this each an everytime you get a new tga file for the different mods . you can use win mip to get a car files imported into the game its just a few more different steps , the above directions is how most people use to get the car files in the game , hopefully this helps if not reply back with the steps your doing and well go from there
