So I found a disc with WMA files that I made 15-20 years ago but for some reason I wasn't able to play the files either with Windows Media Player or VLC due to a DRM issue. I made this disc using the Windows Backup Program, backing up my Music folder, with files that I ripped using Windows Media Player from CD's that I own. The issue that I ran into after unsuccessfully converting the file is that I was unable to delete the file because of the "error decoder appears to have frozen". I brought up Task Manager but there were no programs running (maybe background processes IDK but I tried to also delete it in Safe Mode). I was only able to delete the file after uninstalling dBpoweramp.

Is there a work around for this? Some of the CD's I ripped I either lost or they are broken/corrupted and I would really like to get my music back if possible.
