Forum:DLC/Non-DLC Issue

I have a "compatibility problem". I bought all 3 DLCs, and when I invite a friend (who doesn't have any DLC) to my game, it says him he couldn't connect because we either don't have the same version of the game or I'm in DLC content he doesn't have, even though all my characters are in "vanilla" borderlands zones.

Any ideas? L4C YukiNagato 16:34, April 17, 2010 (UTC)
