Crash de guild wars aider moi
Either post in english or go to the french forum:
http://forum-fr.guildwars2.com/
Also: crash reports should preferrably be done via ingame bug report.
This crash closes the game and doesn’t provide a report feature. Although he/she shoud be posting on the French forum to get the most appropriate help as we may misundstand what he/she is asking. But anyway, it’s a crash because your system can’t keep up with how much data needs processing. It typically occurs in WvW during large Zerg on Zerg events.
