ProMods

So i just downloaded the last version of ProMods , with both Addons, now it says that is not compatible, but only on Middle East map and Promods map. The trailer packages is ok.
I guess it's cause the last version of ETS2 is the 1.37.1 right?
If it's this how tf i downgrade to 1.37?

Whenever the game tells you a mod is incompatible the first thing you should do is click on the I (INFO) icon in the mod manager and the game will tell you why it's incompatible.
Most likely you are missing required map DLCs

have all the DLC and installed look in the DEF file because it is not compatible and it appears that I am missing DLC since they are all installed something strange is wrong

If only the def file is not compatible then you probably selected the tickbox for having the Special Transport DLC in the def generator, while you do not own that DLC.

I have all the important DLC of the game but even so it says that those DLC are missing this is very rare

show us your game.log.
