It maybe best to have more than one RSII install. One to play campaigns in and the other to have just for MP. That way it should be easier to have the same install with MP.
For ages we were trying to get RS to work with MP and no-one was able to get it to work. This was despite the assurances that they had 'vanilla' RS installs. In the end I got together with a work mate and created two exactly the same installs on our laptops and managed to play MP with RS.
