I am also having the same issue.
EU player, Norway.
Error message: Unable to complete version check (20458)(24530)(20457)(410)
Update history (found by selecting options when on the game from the PS4 dashboard): Version 3.40 (my friend's is 3.41)
And launcher version is: 2015.11.07.0000.00000 (my friends' launcher updated automatically before entering in your passwords and such, then a further update started after log in)
I hope we have more reporting this issue so that hopefully SE can address it. It seems to me our game files have been corrupt by the PSN maintenance and/or the update to FFXIV. PRAY we don't have to uninstall and start again. :O
Hope this helps (somehow)
