I'm having the exact same problem, although on a different computer. I can usually play for several hours. But then suddenly, without no previous lag or glitches the game just end and closes down. There are no "Crash" messages or anything. I was told my computer meets the standards and it's fairly new.

I'll try to bring down the smooth edges a bit, although it will hurt my heart

If though some of your symptoms may be the same, your exact cause may be somewhat different. It starts to get confused when 2, 3, 4, 5, 6 start filling up the same thread asking for help. We try to encourage each person to make their own thread.
