This has been made with Ableton Live 12.1b6, which is still a beta version. So itās unopenable for people who havenāt gone beta testing (which isnāt likely for many beginners).
Maybe there could be two different versions for download, one a current live version and one the āimprovedā 12.1 version. At least until 12.1 is actually launched.
Loving the course. Just disappointed not to be able to use the materials.
Welcome to the forums @Palaceofvision
Yes, seems the .ALS project was created & saved with Ableton Live 12.1 which is still in Beta at the moment and no yet released.
Bummer but also makes sense if PLASK decided to explain and showcase latest Live 12.1 features 
Ableton Live license owners can Register for Live 12 beta Program on Ableton Centercode Website to get the latest 12.1bx version ( The Beta installs separately, not overwriting your current Live 12 Release ).
You also get access to new Ableton Live sequencers and other stuffs
Just click on the āNo Account - Create Oneā link if youāre not yet registered for the Beta Program.
Hope this helps !
I know there is a few more videos, but wow P-LASK!
My track is sounding incredible lol.
Thanks in advance and been a fun ride.
Cheers
Welcome to the forums and thanks for your comment ! 
Big help
Update on this :
Live 12.1 has been released by Ableton now 
So you no longer need to get the beta through Ableton Center Code
Hey @Paul_L ,
Just wanted to say thanks for the absolutely brilliant courses! Iād been avoiding learning Ableton for a while, but after taking the Level 1 and Level 2 courses you have made, Iāve totally fallen in love with this DAW. This will absolutely be my DAW of choice going forwardāI finally understand why itās so loved and treasured. Thank you for the amazing work!
Hereās what really made your course work for me:
Beyond YouTube Basics
You managed to cover things that YouTube tutorials just donāt, or canāt, without rushing through. You took the time to really dig into each element, and it made such a difference.
Effortlessly Easy
You somehow made even all parts of Ableton feel approachable. You explained everything as you went along and I found myself not just learning how to use a DAW, but also I learned about compression, limiters and chorus. The way you structured each lesson made it easy to follow and actually absorb everything. Also you explained everything as you went along
Calm and Collected Teaching
Your calm, patient style was a breath of fresh air. You didnāt rush, and that gave me space to really understand each concept. The whole course felt more like a relaxed conversation than a āmust finishā lesson.
No Gimmicks, Just Solid Instruction
I loved that this wasnāt one of those ālearn Ableton in 10 minutesā deals. You took your time, and because of that, I came away feeling genuinely confident in what Iād learned.
Building Block Approach
The building-block method you used was perfect. Each section made sense on its own, but it also set me up for the next part in a way that didnāt feel overwhelming. I could actually see the progress as I went along.
Overall, I think youāre an amazing instructor. Your depth of knowledge and clear, structured approach really clicked with me. Thanks for putting so much care and detail into this courseāit made a huge difference!
Looking forward to more courses from you!
P.S - A big thanks for introducing me to Compressy the elf.
Best,
Forever
Hey @ForeverSeason , thanks for the kind words on the course! It is genuinely nice to hear that my approach to teaching connected with you, and you are diving into your Ableton Live journey. Best of luck moving forward with your music, and please do spread the word about the course. Iām looking forward to putting out some more tutorials on Sonic Academy soon!
Really good course, thank you. As was the previous level. P-LASK is an excellent teacher, very thorough in his explanations, and covers a wide range of topics.
great course!
Awesome course!!!
Thank you!! Amazing class, I learned a lot
fantastic follow on from level 1, took what I already thought was banging and just polished the hell out of it, really interesting and useful stuff, thanks!
Ahh. Itās P-Lask. Iām glad I clicked on this. I like his teaching style.
These beginner courses were awesome, thanks so much! The production beast is feeling a lot less scary now.
Iām an FL user and just getting started with Ableton. I learned so much through both of the courses you put together. You made the experience really enjoyable with a lot of great information about Ableton. The time and effort you put into making these courses is greatly appreciated. Thanks so much!!
Glad it was usefulā¦ welcome to the community.
