Weird problem opening a recent Project

Cubase
1

I created a Project 3 months ago, 3 weeks ago I was recording guitar solo on it. Saved it.

Two days ago I returned from a 2 week vacation and updated from 15.0.20 to 15.0.21. Yesterday and today I have been trying to open the project from the Cubase opening page - it opens - and I find the project does not contain audio. Really? So next, from within the Project, I open the Project Library and try to load an earlier version of the same Project. I am told it cannot be opened. Again, really?

So then I close Cubase Pro 15.0.21…and then drag the first Project I loaded (the one that offered no audio)…and DROP it onto the Cubase Pro icon… And the Project opens, and all the audio is there. WTH?

Anybody else run into this? I’m PC Win 11 version 25H2, the latest version.

Hi,

What exactly do you mean by this?

Are there the Audio Events available/visible? Do they show the waveform? Do you get the Missing Audio Files message? What do you see in the Pool?

The audio event ‘shells’ are there, including the tempo track ‘shell’ but there are no wave files or tempo indicators within the shells.

Also it seems the 15.0.21 version is creating smaller Cubase icons at the start of the Project saved files. I’m sure everyone is noticing this? Hm, I think the smaller Cubase icons showed up in 15.0.20? I didn’t really take note of this until now.

Martin, I did not check the pool at that time but I will today. Ok, I’ve checked this: the pool also shows the empty shells/events.

Hi,

Does it mean no waveform?

Can you see the path to the file in the Pool? What happens, if you try to reveal the files in Finder/File Explorer? Do they exist?

Do you get the Missing Files window?

Could you attach a screenshot?

Here I have an opened Project and I then go to open a different Project from the Open Library in the File header.

Then I close this Cubase Project and closeout Cubase, and now drag the same Project I was trying to open, and drop it on the Cubase icon on the desktop:

Thanks for looking at this Martin. Spending a few more minutes here I notice that if I close the open Project and then try to open a different Project, then that different Project will open. This is a different process than what I remember in years past. If I had an open Project and opened a different one on top of it, Cubase would present a graphic ‘thunderbolt’ and indicate the new Project was ‘activated’. Did this behavior go away, to be superseded by the window that tells me the Project ‘could not be opened’?

I would think my files were somehow corrupted, except, given a clean slate, the drag and drop process works.

Hi,

Based on the user requests, if you open project B over project A, the project B doesn’t become active automatically anymore. You have to activate it manually.

Open Library would allow you to load a Pool, not a project???
