Sudden java error fails the server

I'm pretty much a newbie, but I had Serviio running fine until suddenly it throws the java NullPointerException shown below from the Serviio log.
I upgraded from Serviio version 1.7.1.1 to version 1.8 and it broke at that point. I reinstalled java and Serviio 1.7.1.1, checked for broken packages, and it still fails. (Bad Christmas :!: )
Serviio is installed in my home directory and now fails whether run from the command line or on boot from “Startup Applications”. Anyone have suggestions?

I'm running Ubuntu 16.04 on an AMD Athlon II X2 240 Processor x2, a 32 bit OS installation with a 1TB hard disk.

java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) Server VM (build 25.101-b13, mixed mode)

have you tried removing serviio and reinstalling,
Also more of a security point, personally i would not run any app as root

Thanks. I had already reinstalled Serviio twice. I did it again, but this time I also replaced the library. It worked, and the library is rebuilding as I write this. Must have been corrupted somehow. :P
