shuts down

[azure-balmung]

whenever i try to go in game (after i selected my character and server) ill be at the map loading screen the fiesta will just shut down and have an error thing, saying "fiesta.bin has encountered a problem and needs to close."
ive restarted, downloaded manual patch, got the .net thing and still no luck.
anyone know how to fix it?
