I have lost all of my dlc apart from the preserved collection east coastway. It comes up with a notification saying that some of my files are not up to date and need to be updated to be used and it has the names of the dlc there (southeastern highspeed, long island railroad, class 465/9 and rapud transit). It tells me to close the game and update it, however when I check for an update, it says the software is up to date. Someone please help me!!
