Alright,

How to begin. I tried to log in today, with the updated launcher as usual. I own the game on steam, with all the dlc on steam. In the mog station, it says my account is a steam account. But each time I try to log in, I get the wonderful error code that it cannot verify my launcher version with the error codes posted above [30410][30607][20457][404].
I have made sure that the firewall allows both steam and the game through, and I even took the advice that was given to someone else, following it to a T that I will post below. And I still cannot access the game that I pay money to be able to play.

Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.

Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
Right-Click on the FFXIV launcher icon and select "Properties"
Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
Hit "Apply", then "OK" to save the changes.
Please RESTART your PC now.

This also did not resolve my issue.
