The content appears to be from the file 'maestro-server.log'. This is a file created by League of Legends when you run it from AutoLoL. This is a bug (or a feature, I don't know) from League of Legends, my guess is that the file should be created in your
installation directory instead.
However, this file has nothing to do with the functionality of AutoLoL.
If League of Legends didn't start my guess is that there is something wrong with your installation, or perhaps the servers were down at the moment.
Otherwise please provide more info.
