I wasn't clear enough in my explanation. I have 2 steam accounts already, and these accounts have been running the server & playing the game simultaneously for over 18 months now. It's only with the last patch that I can no longer run 2 instances of the game simultaneously on the same machine (even from 2 seperate steam accounts).
