Cannot start Serviio on my mac
I'm John a happy user

I have a mac osx 10.10.5
I had to restore my mac for a broken ssd, recover all my data from time machine but my Serviio won't start
it said, in a blank sad windows named Electron: Cannot connect to the server, it doesn't seem to be running
tried to delete and reinstall the software (i think i had 1.6.1, download the 1.7) but same error occur
any ideas?
Thank you for the great Job
PS I run a search but didn't find any solution for my problem, found some similar on windows, but cannot help me.
