ive found a solution that work 100% (only for multiplayer) without any "out of synch" errors:
1. download Men of War game client (free of charge)
http://www.1cfiles.com/MenofWar/mow-...1.17.5-int.exe
2. install game (choose other install location as y installed original MoW - when needed)
3. start game with with new shortcut "Men of War. Victory Day Edition"
4. use y original CD-Key
important: this solution is only allowed with legal copy of MoW and legal CD-Key for multiplayer.
