Update to Launcher won't start

[Jendor]

I got mine to work after deleting the entire client and reinstall the game. That was after 12 hrs with constant struggle to get it to update, in vain.
I noticed the file size of my client also shrinked after I reinstalled it (Ps4 ARR CE disc version).
This issue with the Updater/Launcher not updating started with the launch of Heawensward, and continued at every major patch where the client launcher needs to update before I log in.
Previously I've been able to get in after a few hours, but not this time, so I finally deleted the client. That's 5hrs with download and install process.
I really hope this reinstall also prevent the same issue at next update....
