ProMods

I have ETS2 version 133.3.1 and installed Promods 2.32.
when I start the game the mods have a red button and say incompatible.
Can you suggest a solution, please?

Do you own all the DLC you need? You can click on the 'i' and the game will tell you why it's incompatible.

Thankyou so much for the information. DLS-IT was what I was missing. I am happy now, have a good day....John
