Pretty ordinary that so many people are experiencing this problem and no solution seems to be forthcoming. I’ve had this game pretty much since launch and after getting a new computer recently thought I’d boot it up again after a long absence to see if Heart of Thorns is worth getting. This error happened three times in an hour, tried to update my drivers, did some research and come across this thread. Not gonna bother with Heart of Thorns now and might give Wildstar more of a bash. Surely NCSOFT and ArenaNet know bugs like this cost them money….
