ProMods

I didn't read either :/

We're sorry, we can't help you with that.

Well i went ahead and bought all of the map packs, and it still says incompatible, i have restarted my pc and steam

I bought the map booster pack with East, North, France, Italia and Baltic sea

You need road to the black sea dlc for ProMods 2.46 too.

Ah i got it mixed up with beyond, can't afford another £11 today have spent to much, will look back in the future.

Can i play without beyond the baltic sea and black sea

Sure!

Downgrade your game to version ETS2 1.34 and downloads ProMods 2.33 from the compatibility page.
