Hello,

I am a complete begginer in using terminal on my mac but I managed to install AMC and open a project and edit a source file (using a validated template from another user) but it does not run further: I have the message below on my terminal when I want to create the document (and the AMC window says no "working document"). Do you have any suggestion on how to solve this?
Thanks and sorry if this is an easy solving problem!

Bénédicte
