Yes, I use IL2 DCG.
But you have to know that this campaign "MarethLine43" asn't been developed by Lowengrin.
Originally, IL2 DCG is for offline or coop usage.
I host online "Ciel-De-Guerre" joinable with HyperLobby wich is a dogfight server.
I use IL2 1946 4.11.1m Dedicated Server + IL2 DCG + IL2 SC.
So "Ciel-De-Guerre" is the only one dogfight server wich offer really dynamic campaign. And the problems spawn when sometime my modifications of the original scenario don't respect the rules (from Lowengrin or IL2 1946.

)
Thanks all for your help and happy new year 2013.
I'm unable to laod and edit all missions with FMB. Do you have the same problem ?
