Explorer map maps (cont+, etc) in Multiplayer? Some help pls

So I read a bunch of people that said change the script to allow multiplayer (from false to true). I did that last night and my buddy did the same, but we kept getting an error that said "another player doesn't have a DLC" kinda thing. I couldn't even start a multiplayer session myself so it seems this fix doesn't work - or I messed up, but it was such a simple script fix I can't image I did.

Any help would be appreciated. Thanks.

I have no experience with this myself, but would it help if you moved the mapscript from the DLC maps folder to the ordinary maps folder?
You would need to disable Denmark as well (if you took the Denmark + explorer map pack offer and someone else didn't). The same with other civs not all of you have.

,,, there is more to change that it works.
I even managed to be able to use any Hotseat Map over Internet with my brother.
We only had to copy the desired map to the map Directory

I would have copied here, what to do (ONLY THE ONE WHO HOST THE GAME HAS TO CHANGE THE FILES, but all need the same map local !) ... BUT I COULDN'T FIND the thread now, it seems it has been deleted ??? WTF
