Guild Wars 2

I would like to ask for some assistance, Today I tried to do the Fractual dungeons with a friend and some of his friends, but, every time I clicked ready, I kept getting this Code=19:9:18:1803:101 and my game crashes, can anyone help me figure out what’s going on?

Use that link to submit a ticket to a GM.
It takes a couple of days but the sooner you get it in the sooner you’ll be satisfied
When you submit your ticket, send screenshots too (if the form allows). The GM who contacts you will want screens of the error and what you’re doing just before it.
Good luck!!
