One or more required files of the promods are missing

[Tim1999]

It works alright in SinglePlayer mode as far as I can tell but whenever I try to join multiplayer an error pops up telling me this : " One or more required files of the promods map modification could not be found. Do you need help installing it?"
I have all the DLC'S required to run the mod , the mod is up to date ( 257 on ETS 1.42) and I have generated the def file correctly, but in multiplayer it do not start, selm problem by my friend.
