Greyed out Tracks, not deactivated though

I have an issue where I had been making a song in cubase 11 pro trial, but the day my trial ended, I tried to open Cubase 11 pro, and it told me I couldn’t use it anymore.
So I bought the Cubase 11 pro version, and I activated it, but now some of my tracks are greyed out.
Is there anything I can do? I don’t want to have to start over.
Now, I would create new tracks for that, but unfortunately, I can’t see what setting that instrument has, (they had very specific settings) because the track is greyed out.
Any ideas?

Are the tracks disabled? Right click a track and see if there’s an “Enable Track” available in the menu.

No, that was the first thing I checked.
