Cubasis app will no longer open

I was working on project with audio tracks only. Had recorded four tracks with acoustic guitar.
Then it started freezing when I added a 4th and 5th audio track, as if it didn’t have enough “power” to run the program.

I then deleted some tracks and ended up working with only 4 audio tracks and it ran fine after that. Then I left it. And when I returned Cubasis simply wouldn’t open.

Unfortunately I can’t provide you with a crash log as I have no computer.
