Guild Wars 2

When I’m playing in the mist’s or a battleground it allways happens a crash like this… I don’t know what it is, i’ve been searching the forum’s, but I can’t find anything that can fix this crash.

Please help me.
Thank You.

I can’t even join PvP. Each time I press join solo or team arena I get an error. It started happening today, after about half an hour of extreme lag (only in pvp).

im haveing the same problem and im talking to gw2 via email about it and they said to update my OS and all my drivers.. i was also talking about this problem on forum and someone said i could be beacuse of the gamebooster so i uninstalled it now..
here are some links for dirvers updates:
- AMD autodetect: http://support.amd.com/us/gpudownload/windows/Pages/auto_detect.aspx
- Nvidia Autodetect: http://www.geforce.com/drivers (Click “Auto-Detect your GPU”)
- Intel Autodetect: http://downloadcenter.intel.com/default.aspx?lang=eng

and for windows update just go to start and write in windows update..

Hope this helps
