Smashing. Thank you. I think I see your problem now...
See, in your first screenshot, directly above the left hand end of the 'before/after' tooltip, there's a drop-down menu there.
Yours is set to
"Update database to point to a new location (No file rename, move or copy)"Change that to
"Rename (Moves file if directory changes)"To relink the track that you tested with above:
Either browse to said track externally from MC and manually append the " [renamed] to the file name...
or
Remove the "[ renamed]" part from the title in MC, then run the rename tool again, exactly as you have it set up in your first screenshot, and that will correct the database error shown in your second screenshot.
Let us know if you need any more help.
Near the beginning of the wiki article, just after the "Caution" notes, "Modes" are explained. This could have helped you...
The Rename, Move, and Copy Files tool can be used in one of four primary modes:
Rename (moves files if directory changes)
Renames and moves files, including from one disk to another.
Copy
Creates new independent copies of the selected files. This mode does not alter the Library or the source files on disk.
Copy and update database to point to new location
Creates new independent copies of the selected files, and replaces the Library entries for the existing source files with the new files. This is identical to Rename mode, except that it leaves the original copies behind untouched.
Update database to point to new location (no file rename, move, or copy)
Only changes the [Filename] path for the selected files in the Media Center Library. This mode does not move or copy any files on disk.
