Unable to Complete Version Check [30605][20448][10009][10019]

Hi, I know this kind of thread is already exists, but it seems from SE itself never actually fix this error. Now lets get to the point.

After major updates 3.1, I cant open the launcher, it show error, "Unable to Complete Version Check [30605][20448][10009][10019]", I tried to fix this error by using many solution methods in the forum :

- Restart PC 2 times
- Restart modem
- Flush DNS
- Re-download launcher on FFXIV website
- Renaming FF14 folder in My Document/My Game/
- Change BootVersionCheckMode from 0 to 1
- Delete everything in ffxivgame.ver
- Fix Registry
- Allow program through firewall
- Reinstall the game 2 times
- Delete Registry
- Copying my friend FF14 client (before update 3.1)
- Uncheck the 'read-only' options
- Disabling AV

And many more, I can't remembered it anymore. I don't know whats wrong, I've tried every solutions I can find on the internet for this error, yet I can't fixed it. I feel really frustrated because this error is just too ridiculous :mad: Can anyone give me a hint or something about this problem ? I really appreciated it, thank you.

--- EDITED ---

Somehow it fixed it after I copy my friend client "..\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot\" folder and "C:\Users\asdasd\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn\" folder.

Then I delete everything in "My Games\FINAL FANTASY XIV - A Realm Reborn\" except :

• 'downloads\'
• 'screenshots\'
• 'FFXIV.cfg'
• 'FFXIV_BOOT.cfg'

And it will launch normally like no error at all, really weird, it seems the real problem is in "My Games\FINAL FANTASY XIV - A Realm Reborn\", but well, still no answer from SE, but at least I can play the game again.
