Constant Crashes in the Praetorium. Can't finish Story

Time:6/27/2014, as well as several months back.
Frequency: Always
World name:Goblin, and then Balmung
Character name: Azrhi Vinland
NPC name: N/A
Monster name: N/A
Class/Level: 50
Party or solo: Raid
In-game time: no idea
Area and coordinates: The Praetorium

Every few minutes windows pulls me out telling me FFXIV is no longer responding and I have to close out. Only everh appens in the Praetorium. v.v I quit because I couldn't progress a few months back due to it, and it's still happening now.

Specs:
Asrock 890gx pro3 motherboard
Radeon ATI XFX HD6870 Black Edition graphics card
AMD Phenom II 1100T processor
Not sure on the RAM..


Can someone help? >.<

UPDATE:

I managed to finish the Praetorium, but the bug is still present. Confirmed by re-entering the dungeon and I got borked. This leads me to believe it may be something to do with the starting area?

Suffice it to say, after taking the shortcut when the first chunk was done, it was smooth sailing.

That being said though, it'll be hell if I get the place in roulette, so... Still want halp. -nods- v.v

Have you tried deleting all game files and reinstalling?
