If your project is corrupted, you can take the following actions.
When you open a project file, Minitab automatically creates a backup file in the same folder as the original .MPJ file. The backup file has a .BAK extension. For example, if the project file is DEFECTS.MPJ, then the backup file is DEFECT.MPJ.BAK.
If you think that a project might be corrupted, try to save the project and send a copy of the .MPJ and .BAK files to firstname.lastname@example.org. Minitab Technical Support might be able to recover some or all of the project's contents.
If you cannot retrieve a backup copy, you can try to recover individual worksheets.
You can select multiple worksheets by pressing the Ctrl key as you select them.
After you recover a corrupted project file, update the software and the project to prevent the project from becoming corrupt again.
