hmmm...

based on his post here...

While i haven't experienced this exact issue myself, i did find this topic which has some leads on it from someone who describes what appears to be the same issue you are having.

Hopefully this helps, or maybe someone else has an idea and can pitch in here...
Are you by chance playing on a modern(ish) nvidia laptop?

... I did have the Abyssea ultimate collection. Seekers of Adoulin expansion wasn't released about a year later when I started FF11. So all this time, I was installing Abyssea collection 1st, then I added SoA installation, in which after... I replaced the installation data with my backups that has the most recent patch. I never did ran the game straight after installation, it's always after replacing with backups.

Not sure if this would help, but maybe you can somehow get the game backups from someone who still plays FF11, usually located in this folder: C:\Program Files\PlayOnline\SquareEnix\FINAL FANTASY XI\
That said person might wanna take out his/her screenshot collection which located somewhere in PlayOnlineViewer folder though. And don't have to worry with login information since it will always ask you to re-register your POL ID.

Another thing: I also discovered back then that you can't install FF11 outside it's default installation path. I tried this before (since majority of my games usually installed not on my boot partition) and unfortunately the game won't run at all. Since then, I don't have any choice but to install the game on it's usual "C:\Program Files". IMO, this is one quite major issues need to be fixed. ^^;

Sorry, can't really help much. Hope you'll find and fix the issue tho.
