Serviio won't start after upgrade (Linux)

OK, I have upgraded before, but it's been a while, so maybe I messed something up, but I can't get serviio to run after the upgrade to 1.7. Here's what I did:

1) Stopped my server with "sudo systemctl stop serviio.service"
2) Moved old serviio installation folder to a backup location.
3) Unzipped serviio 1.7 files to serviio install location (in my case, /usr/local/serviio)
4) Copied library and plugin directories from backup to install location.
5) Restarted server with "sudo systemctl start serviio.service".

When I go to MediaBrowser or Console, I get nothing--the server doesn't respond. I can copy everything back and it works fine.

Anyone have any ideas?

Thanks for any help!

It's easy.
I had the same problem but worked after a simply forgotten thing:
Make the files in the /lib folder executeable.

Give all the old permissions --> chmod 755.
