ffxiv.exe fatal errors

[Iraphine]

I was playing fine all day today, then when teleporting to MD to start my MSQ, before even loading into the zone I got this error. Tried restarting PC, using DX9 instead of 11, updating graphics card, compatibility mode changed to windows 7, and still a no-go. I didn't change anything from how I normally play, however the error keeps appearing after getting past the queue and getting the 'Now Loading' screen into MD.
