Server 1.5.2 doesn't work on my Mac

I used Servo 1.3.1 on my Mac Pro (2006) because this version works and I had some difficulties with a newer version (I couldn't add a profile in profiles.xml because the file was included in server app and modification prevented the app to run.
Now I use an iMac under 10.10.5 and I copied the two apps (1.3.1) and it works. But I wanted to try an update, so I downloaded and installed the last version (1.5.2). But this version doesn't work for me. What is new is that there is no more app for the server. The files are in /Library/Application Support and it is theorically started by a file in /Library/LaunchDaemons. So it's started with the session. That's what is said.
When I run Servo Console, it can't find the server and quits.
So I think that, perhaps, the server is not correctly running. Then I use the command found in the FAQ,
"sudo launchctl load /Library/LaunchDaemons/org.serviio.server.plist"
And the Terminal confirms that the operation is already in progress.
But the Console doesn't find him again, event after restarting.
So I uninstalled the version 1.5.2 and copied again the old (very old) version 1.3.1 which works very well.
But I can't understand why I can't use version 1.5.2 which should be better, it's the object of updates

Perhaps I don't know how to use the server in its current appearance...
And, in version 1.3.1, I am the owner for read and write. In version 1.5.2 the system is the owner.
I laughed the command java -version in the Terminal and the answer was
java version "1.6.0_65"

Is there something in Serviio log?

Yes, there is many lines in servo.log file, but they don't help me to understand

It looks like the DB is corrupted. I'd suggest do a clean re-install.

Thanks, so I did it.
It works now. So I copied my Samsung profile from the old profiles.xml (included in the app) to the new profiles.xml (in Application Support), but changes aren't seen aven after stopping and starting the server or quitting the console. I think I must restart the Mac. I preferred the old way, when the server was an app too.
Edit : In fact, I forgot I could stop and start the service via the Terminal. I did it and now my changes are managed.
