@UrushibaraRuka you may need to enable "Wait for network" in case your new router needs a little more time to allocate an IP address.

I'll add a fix for the division by zero - that shouldn't happen but my guess is that you managed to download zero bytes most likely because of the network issues.

Tried that but it didn't change anything. It also doesn't matter if I try to update right after booting or after hours of amazon prime.

And because I use "Yatse" to control my HTPC I also gave it a fixed IP as I did before. Well...it's still DHCP but my router is set to allocate the same IP to my HTPC and
from what I see in my router (which is quite a bit faster than the old one which was also a Fritzbox) that IP is allocated nearly the same moment I turn my HTPC on.

Also, since yesterday I'm missing several addon-icons that where there before (Amazon and Youtube Icons for example).
I'm currently guessing that my little 32gb SATA SSD Module (not even a real SSD) might start to fail as that might also explain the "buffer read/write" errors I sometimes
see in the Log (not debug logs though but regular logs) which only occure when I watch something on Amazon or Youtube, playback stops for 10 seconds without warning and then get thrown back into the main
menu. 

I'll update to the latest build by hand again and test again.

UPDATE:
The update works again with the latest build (no other change).
