Guild Wars 2

Why I get crashed right after killing mouth of mordermoth and since then I cant join on my fellow party mates??? it says Network error which clearly is not.

There is a 64 bit beta version of the client for Windows you can download in your account management section that seems to prevent this crash. I had your problem and after my second time crashing (right as he died and got no loot/thrown off map) I installed it. I have run him 6 times since, no problems.
