I have two different copies of the game on two different computers; one is the Steam version and one is the regular one. I tried playing the Steam version today and the only content I have is the Brabham series. I looked at the content and it says everything is installed but they don't show up. My other question is where to I put mods on the Steam version; it must be a different location the the regular version. I would appreciate any help you can give me. Thanks.
