Same as some other people here:

C++ Runtime Error crash when playing for maybe 30 minutes upon loading a new zone. Restart computer, got a error 2146697211 from the FFXIV launcher. Wouldn't load. Then would load but would have a blank screen. Then would go further with a blank "play" button. Then Errors 2002 and 5006. Then finally got in to press the start button and immediately 1017. Then was able to get to the frozen Character Screen with a 1017. Then last and finally, Unable to contact EU/NA servers. Awesome. 2 quests in 2 hours this morning.

EDIT: Gents, it's NOT us....their ridiculously generic "reset routers/connections (power up/power down)" is positively moronic.
