xl mod and multiplayer

i got xl mod and now the multiplayer wont let me join any games or anyone join any of my games(even when i use regular early, high ,late not xl early) is there anyway i can play multiplayer with this mod?

if they have the mod, then they can join........if they dont, they cant, you can uninstall the mod and reinstall medi....or....REINSTALL medi into a different folder (thus you have 2 installs of the game) you must create a disktop short cut for each and launce the game you want to play form that.

cool thanks
