FIrst please use search button on forum because many same questions is solved.

Steam automatic upgrade your game and thats the reason why you can't play anymore TruckersMP.

You have be patient until TMP Developer team makes TruckersMP compatible with latest version of ets2 and ats.

As soon as possible you will able to play this awesome mod.
