The reason for getting this error is that the license file was in Rich Text format but you actually can't tell on a Mac computer.
(Vendor daemon name) EXITING DUE TO SIGNAL 36 Exit reason 4
(lmgrd) LUXION exited with status 36 (No features to serve)
(lmgrd) LUXION daemon found no features. Please correct
(lmgrd) license file and re-start daemons.
To resolve this issue, you will need to download Textwrangler and resave the file by making sure to use Line break "Windows (CRLF).
The other way would be to contact Luxion license support and they would be able to create you a new license file to help resolve the issue.
