The maps appear in the server setup screen but the names are messed up. The single player won't run but I can start a server, non-functional I would guess, and run around the new multiplayer maps fine. After launching it as a mod the Resurrection of Evil text that appears over the Mars globe in the game menu seems to flicker in and out and not render properly. I tried putting the d3xp folder into the Doom folder, like you would install a mod, and it lets you choose the Resurrection of Evil in the mod list after you launch the game.
