I know it is silly to ask a question because nobody ever gives a reasonable solution but here goes anyways.

when I select all cars and tracks all that shows is the test cars from the EEC gt3 game.

@Pawgy It sounds like the EEC mod might be in the wrong directory or has overwritten some vital files. The safest thing to do is delete the EEC mod and then verify Automobilista's files via Steam.

In Steam, right-click on Automobilista, select Properties, select Local Files, then click on "Verify Integrity of Game Files".

It can take a few seconds for that to load, if you wait and when the button appears to glow slightly you should be able to select the cars you want.
Hope that made sense.

Or what Stephen said.

Yes, selecting All Cars & Tracks will take longer to load than just a normal car/track combination.
