You have been BANNED from Limsa, no more Lala fells are allowed! :P

In all seriousness, this is a job for FFXIV service support. E-mail them you PC specs and wait for a reply. I had to reinstall my FFXIV software before(collectors edition) and it works at all settings. My PC isn't the best but it gets by. Everything is basically in it's own partition (it's own drive)of the HDD. I never had to mess with files or anything of that nature.

I also played from BETA but with the C.E., everything is on a clean slate along with the updates. Good luck and keep the thread up-dated. o.o
