Thank you for the additional reply gurukevy,

If you are still experiencing an issue with connection, please make sure all background applications (including anti-virus programs such as Norton, Kaspersky, Windows Defender, etc.) have been disabled and/or closed to minimize game interference before attempting to log in. Once your PC has been restarted, Right-Click the FFXI launcher icon once more and select “Run as Administrator.” This option can also be set permanently by Right-Clicking on the FFXI launcher icon, selecting Properties, then under the Compatibility tab, check the box that says “Run this program as an administrator” and clicking OK.

Thank you again for posting the FINAL FANTASY XI Technical Support Forums!
