Yep I have GW1 and can play it for hours with no errors.
Location: Florida
I play during the day mostly (and some nights) during the week all the time but not much at all on weekends.
I get this error CONSTANTLY. The game is nearly unplayable for me but I am a dedicated GW fan and will continue to log on every 10 minutes when i get kicked from WvW. It is kicking me from pve maps (all of them) the last two days also. I get this code 7 every half hour at a minimum and when its bad i get it every 5 or 10 minutes for hours at a time.
Thanks for your attention to this matter.
