All I did was walk through the Asura Gate to Lion’s Arch, and now it seems I’m stuck on an nearly-infinite loading screen. After about 10 seconds I can hear some sort of in-game sound I assume (since I’ve never visited Lion’s Arch before, I’ve only just bought the game today), and after a few minutes I simply get the 7:11:3:189:101 error and the game exits to the launcher. Everything was working fine, I played continuously for two hours with no issues at all, and now I’m stuck.. forever?
edit: It seems to have magically fixed itself now. I’d still like to know what’s causing this, so I won’t freak out when it next happens.
