Help The Loser.) (Spintires: MudRunner)

Hello everyone!)
Faced here with what problem on the MudRunner with the installation of additional cards.
On the map (e.g. Shadow of Chernobyl, the Town, Winter's tale) at the time of card selection, no "entry-trucks", and displays the appropriate message: "Select at least one truck to start the game", but empty slots are not observed.( Don't know what to do.(
Three maps previously downloaded all worked (it's the Moon (LaLuna), Voronezh, and IntoTheWild) great passed.
What I'm doing wrong, please tell me.
Thanks in advance.
