I still see people complaining that they can't play because of the yesterday's patch.

Even if there's a big banner ontop of the forums and many truckers already posted status like this one, here's how you can downgrade your game to the 1.26 version :

Right click on ETS2 > Properties > Betas > Select temporary_1_26 - 1.26.x for incompatible mods > Boom it's done you can play TMP.
