Do you have a ROM9 folder within your FFXI install? If so, move/remove it, and try loading XI again.

I ran into the same issue on my test install client.

I had a copy of the ROM9 folder in my main copy of FFXI. Once removed FFXI loaded normally.

So much for the ROM9 folder being useless at the moment. I'm guessing the adding for the logo for the new expansion in the last update has started FFXI to look for the ROM9 folder.

Thank you for solution saved me hours of reinstalling.
