TL;DR:
Use VPN to update and switch back once you finish updating!
GUYS, I’VE TRIED EVERY METHOD I COULD FIND AND TRADED EMAILS WITH THE SUPPORT TEAM MULTIPLE TIMES AND STILL NO LUCK
BUT I FINALLY FIXED IT
CrimsonGhost.7169 ’s comment directed me to this reddit page: http://www.reddit.com/r/Guildwars2/comments/2saub4/how_to_fix_your_updater_temp/
So i tried the fix and it didnt work, how ever as i was scrolling down the comment i saw : Vryzakis ’s post and it said to use a VPN
WHICH I DID AND IT FINISHED UPDATING IN FEW SECONDS!!
YES!!!!
and worry not, you don’t have to play with vpn for the rest of your life because once you finish udpating, you can just switch back and turn off the vpn
p.s its better to not sign in when you updating with vpn just in case someone steals your detail 
Upvote if this works for you and you’ve already tried every single other method!
