I have the same problem as Charles, I have tried this and I'm afraid it didn't work for me, how about you Charles?
I'm running windows 7 64bit
my ping is about 40-50ms
my internet connection itself isn't terribly fast thou being in rural England, I get about 6meg down and between 0.4 and 1meg up. I suspect this could have something to do with it.
does anyone know what ports the game uses
