I had this same problem this weekend. The server was running 1.702, and it was a DISASTER. I was trying to set up a multi-ship game with maybe 15-20 people with a combination of ipads and windows laptops. At first, the simulation stopped running after a few minutes each time (and people kept losing their connection to the game repeatedly), but the software itself didn't crash. then suddenly the whole game would crash on the server every time I started a simulation after about five seconds. I tried uninstalling and reinstalling the game twice and restarted my machine several times. I even tried version 1.7 to see if it would work any better to no avail.
Eventually, we tried using a different machine for the server, and it worked fine. I'm not sure what's going on, as I have a very nice computer running windows seven and a pretty good router. It's possible that the problem lies somewhere other than the artemis software.
The game I was hosting was at a retreat for gifted kids, and after we finally got it stable, it was a huge success. I'm planning to host another game at a similar retreat this weekend but will not be able to unless I can fix this, and I have less than 36 hours before I'll have to leave town to head there. Any help would be appreciated. As I write this, I looked at my windows event log and am seeing all kinds of application errors from artemis (along with a few others).
Edit: also, even with the new machine we were unable to get more than 10 or 11 people connected at a time. Any more than that and it would get laggy or buggy.
