The "locked" message always is displayed with Arabesk 6 (and newer) if an existing Arabesk Disk project does not exist on the currently selected hard disk - or if this has been changed. For a "blank" Arabesk disk project - this message will not appear.
In the past, you used to add a movie in Arabesk and create a DVD / Blu-ray. That may be weeks or months ago, but in Arabesk the disk project is still there - even if the project is long gone in Bogart and something new is in the works.
However, if you have created a disk project and have not deleted it, then when deleting / modifying the project in Bogart or changing the hard disk (with Store'n'Share or Disk-Juggler), this information will appear.
- If you do not need the disk project any more, adapt the project to delete the old Disk-Project and can start a new disk project.
(The data in Bogart projects will not be changed
) - But if you want to keep the disk project, you can also keep the data as a "locked" disk project.

Such locked (and encoded) disk projects can still be burned or exported as ISO.
If you are not sure, you should not adapt the project. Then this is locked and you may remember again what, that movie that was. If you no longer need it, you can delete the disk project. If you want to keep it, you simply switch to an empty disk project. Starting with Arabesk 6, you can use up to 10 disk projects at the same time in Arabesk, if you have to burn a disc again.
