Guild Wars 2

For the past few days I have been trying to update the game but every time I try, the update stops after it has downloaded 20 mb.. I dont know what to do.

I have the same problem… the update stops after it has downloaded 30 mb.
Please help us

+1 to the problem, try do to that guide https://help.guildwars2.com/entries/28148006-Repairing-the-Game-Client, it didn’t work for me but may for you.
p.s the first time that happend was on the september patch and it worked it self after a week or so, but now with the halloween it’s just not fair ):

Try posting over in the Tech Support sub-forum, as this would not be considered a bug.

Also, you can peruse the Knowledge Base located: Top of Page – Services/Support

Good luck.
