Updated to 8.7 and server wont start

I am gett the oddest thing today after updating the server… it is not launching the actuall dedicated server, is goes up and shuts off

I see this in the logs:

24-18:34:03.499 11_34 -ERR- Error while reading server configuration from C:/empyrion/dedicated.yaml

That line is specifically a commented out line

# Idle playfield servers held in reserve. For busy public servers, we recommend at least 2 (default = 1)

Any Ideas here?
