I'm assuming your tablet probably updated to Android 11. If MobileSheetsPro is referencing mobilesheetsfree in the path for the files, that's a problem as the paid version no longer has access to that location with Android 11. So what you will need to do is manually move any files that are under /storage/emulated/0/Android/data/com.zubersoft.mobilesheetsfree/files to /storage/emulated/Android/data/com.zubersoft.mobilesheetspro/files, then go to Settings->Other Settings->Fix Broken File Paths, select "Manual", enter /storage/emulated/0/Android/data/com.zubersoft.mobilesheetsfree/files as the "Current folder", then tap the folder icon and navigate to /storage/emulated/0/Android/data/com.zubersoft.mobilesheetspro/files and tap OK. If you run into a permission issue where MobileSheetsPro can't navigate to that path, tap the SD card icon at the top and you should see an option to go to the application data directory which will take you straight there. After selecting that folder and tapping OK, you can then tap OK on the "Fix File Paths" dialog and it should update the database to swap the files to the new location. Now try loading your songs and see if they are fixed.

As a side note, if you go to Settings->Storage->Set MobileSheets Storage Location, is that set to /storage/emulated/0/Android/data/com.zubersoft.mobilesheetspro/files? It's very important that it isn't trying to point to the "mobilesheetsfree" folder, so I just want to verify this. If it is pointing to that folder, you need to switch it to the default by tapping the SD card icon on the dialog, then tapping OK. It will say it will try to move your fails, but it will fail, so you will still have to manually move them all, and you will probably still have to follow my instructions above to fix the database.

On a side note, how did this situation occur where your files were referencing the free directory? Did you swap things over or did that happen as a result of restoring a library backup file from the free version?
