That's because you used the updater in the first place.
The updater currently has an old version on it, so using the updater would actually de-update you.
So reinstall the game and don't use the updater.

Thank you, that worked! I actually got in, but now will have to look for help on how to change the windowed game to full screen

I am having the very same issue with the Updater.
I downloaded and re-downloaded the PS Download file for Windows from 3 of the download sources provided on your page. Having tried one at a time several times over a span of hours I would uninstall and reinstall a new download for Windows only to receive the very same problems. The Updater says it cannot connect to any of it's sources including mirror sites, then says 'ran out of mirror sites'.

I would very much like to be able to join this game as I've somehow been able to actually create a character, but have yet to be able to connect and use the Updater to actually enter the game with her.

Help on this issue would be greatly appreciated.
TY
