Regarding the DRM issue itself:
- If the
.wmafiles were ripped years ago with "Copy protect music" enabled in Windows Media Player, the DRM licenses were tied to the original computer. - Microsoft discontinued parts of the old Windows Media DRM licensing infrastructure many years ago, so in many cases lost DRM licenses cannot be reissued or restored.
- There is no Microsoft-supported tool to remove DRM from protected WMA files.
If these are truly your own recordings, you may still have some options:
- Check whether the files will play on the original PC where they were created.
- Look for the original audio CDs, source recordings, backups, or unprotected copies.
- If the files still play somewhere, you may be able to create new copies in a modern format from the original source recordings.
