thank you so much!
I tried to open your corrected file, and got this error message:

I got it to open.  And the score notation nows shows, and the sound is properly routed to my DAW.  What did you correct??? Thanks so much!

You wrote some wrong things inside your def-score, compare the def-score of my corrected file to the old one and you will see your errors.

 

Happy study.

Also I can see you try to open the file in the assistant. You have to create a new workspace for your studies and work inside this workspace, not in assistant.

For a good understanding of this, I recommend my "Introduction to Opusmodus" on ComposerWorkshop.com

 

Best !
