Apologies, looks like I missed a 1 reading your previous post
Hopefully I got the number and project name right now, but Sonic Academy Video 1.11 (Mixdown, Last-Minute Changes, Micro-Editing).als project just opens find inside Live 11 as well as Live 10 here on my end.
Corrupted archive, problem during extraction ?? No clue but it's the final Mix Down and definitely not a blank project and just opens fine here ( tested in Live 11.0.11 and Live 10.1.41 ).
I would advise trying to re-download the resources and try to use another archive manager app.
