I would like to play DMUC for single player, but DM for multiplayer. When I choose DM multiplayer in the launcher it dosn't work - we can't connect to each other, so I guess I have to install DM from scratch. Will that overwrite or disable my ability to play DMUC? Or can I have both DM and DMUC at the same time, and just select which launcer to use, depending on what I want to play?
