I thought I would show my appreciation for this awesome mod by providing a work around for a problem I ran into and I've seen mentioned on these forums.
This only works provided you do have an internet connection
the scenario for this solution: You wish to play over Lan with two or more players on a single relic account but get the 'cannot verify media' message when trying to log in offline.
--If you wish to play with more than one machine on the same steam account then all but one need to be running steam in offline mode--
1. on machine A start EasternFront mod as normal and log in to your account. As you are, online the game verifies and you are able to log in.
2. Click on skirmish to get to the game setup menu.
3. at this stage unplug your network cable
4. begin the skirmish game.
5. Once the game has loaded, quit back to the main menu.
the game will have noticed you have no network connection and put you in offline mode (red light in the top right)THIS MAY TAKE A FEW SECONDS TO CHANGE, BUT IT WILL. You can now reconnect the network cable to machine and the game will stay in offline mode***
You can now log in on machine B as normal with the same account, using a different profile, without relic kicking machine A
you now have two machines game that are able to play LAN games.
For more players repeat steps 1 - 5 on each additional machine.
A hideous work around I know but I couldnt see any other 'solution' for this issue - hopefully it will help someone with Steam play this great mod on LAN without having to purchase an extra copy of COH.
*** I do not know how long the game stays in offline mode once you have reconnected the cable... it is long enough to start a game and does not stop a game in progress but after the game has finished and players return to the main menu machine B will have the logged in else where message... meaning you'll have to repeat the whole thing to play again.
If any of that isn't clear I'll be happy to clarify.
