okay, i was having the same issue more or less as you guys i think. Launcher will not connect/login My error code was 42:1000:xxxx:xxx can’t remember exactly. anyways, i found my problem.
I use a program called PeerBlock, as a coincidence i had it turned off the first few days i was playing. My computer restarted for an update and when it did PeerBlock launched on startup and started blocking NC INTERACTIVE, INC and every different little connection it tried to make… don’t know why i didn’t think of it sooner. Anyways, i clicked login waited about 15 seconds.. disabled peerblock, instantly connected.
My advice to all of you guys, if you use a probram like PeerBlock, either disable it or make sure it makes an exception for gw2
