Ive done exactly what I am supposed to do, put the layouts in the data/layout folder, opened up the autocross track in single player, pressed Shift+U and clicked load layout, but the layouts arent there. Its just empty. What am I doing wrong, this iis really frustrating me. Any help would be greatly appreciated.

Turns out im just an idiot I thought all the layouts were for the autocross arena, but just noticed that some are for the Blackwood carpark.
