Serviio

I'm trying to update from v1.92 to 2.0 but nothing I try works. I downloaded the file, opened it and clicked on the serviio.sh file yet the screen still displays v1.92. Doing research here I found a comment to stop server, replace all the files except for library and plug in with the files from the new version, tried that - no luck.

How exactly do I upgrade on linux Mint 18?
