Hello Mr_Banks ,
Promods is working for all players who playing in SP cause SP not required the all DLC's in my knowledge. And I didn't know you have the all required DLC's to play latest version of it on MP. If you didn't have the Road to the Black Sea DLC you can't go to the server with the latest Version of Promods .
You already have ALL MAP DLC's check the def file (try to replace)
if can post the an error report message to the question it would be nice ?
Also Check the TMP site article - QF_Giulia already sent to you. ?
