MediaServer fails to load on Linux (Help)

Serviio 1.5.1 is installed on Debian 7.
Java version is 1.8.0_31.

  Code:

crunchuser@desktop:~$ java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)


Attempting to run Serviio.sh results in "Error: Could not find or load main class org.serviio.MediaServer"

  Code:

crunchuser@desktop:~/bin/serviio-1.5.1/bin/serviio-1.5.1/bin$ sh ./serviio.sh
Error: Could not find or load main class org.serviio.MediaServer


I am unable to find a serviio.log file, so I am either not looking in the right place, or one is not generated. I don't know where to go from here. Can anyone help me trouble-shoot this?

What is you just execute ./serviio.sh ?

It looks like it doesn't add the serviio jar files on the classpath.
