Error Code:POL-1155. R:ROM/171/77.DAT

I get this error code and file whenever I try to complete the 05-09-11 Version update. So far it has only effected my 360 version of the game as my PS2 updated just fine. (as of yesterday) I have restarted the update several times, reinstalled the FFXI software both with and without user data intact, and still I get this error message. Anyone else have this problem? I saw the PC error and solution posted by Elennar, however the 360 version won't be that simple.
