Promods is saying incompatable version when I try to play it

[Murray5521]

hello I have all ets2mp dlc I have extracted the promod files to the euro truck simulator 2 mod folder and copied them out of the folder to the main mod folder when I extract the files the promod files are in another folder which I have moved the ones I extracted over but for some reason whenever I try activate the mods in the mod manager it says not for supported version please verify integrity through steam , it does not recognise that I have bought all the dlc for euro truck simulator 2.

not sure what I am doing wrong it is using the temporarily 1.25x beta version for incompatible mods im I using the wrong version of euro truck simulator 2 which beta would I need to play on the promods server I'm confused and have no idea what I could be doing wrong or why it wont let me play any help will be appreciated thankyou

1.25? It's over 4 years old. You need 1.39.

No, it's the option 'opt-out of all beta' or 'no beta' or something like that.
