POL Crashing

Hmm, ive just been playing on my laptop, no problems. But jumped onto my desktop and loaded up FFXI, as soon as i log into my character, POL crashes... Was fine last night and no problems on my laptop... Anyone else having difficulties?

EDIT: Ok, its windower... i can play full screen without windower... but crashes when i open via windower. =/ No idea what it could be considering it was fine last night.
