(SOLVED) Launcher Update Stuck At 55%

(Edit: 4 hours later, after a installation, I finally got the game up and running. There is no need for further aid.)
Problems have risen up for me haven't they?
I was trying to update the GamezBD launcher for half an hour now with no success.
The download speeds are very unstable as it keeps going from 1.67 to 0.8 Mbps.
I tried force checking the client with, again, no success.
My internet speed is 31 Mbps.

 

It is usually a lot easier to download the updates with a torrent client: https://forum.gameznetwork.com/threads/about-the-update.239942/#post-2219321
