Close Windows Media Player if it is currently running.
The DRM folder on your PC is hidden by default. Please take the following
steps to make is visible:
1. Click "Start", then "Run".
2. Type "control folders" in the box and press Enter.
3. In the window that appears, select the "View" tab.
4. Select "Show hidden files and folders".
5. Un-select "Hide protected operating system files/folders". 6. Un-select
"Hide extensions for know file types".
Next, locate your DRM folder:
Under WinXP/2000 this folder should be located at C:/Documents and Settings/All Users/DRM
If you cannot find the DRM folder, please go through steps 1 to 6 above
carefully, ensuring that the correct options are set.
Once you have found the DRM folder, please rename it to "DRMBACKUP". If you now attempt to play your tracks Windows Media Player will perform a security upgrade, which resets all of the necessary DRM files. Each track should then request a new license when you first play it and will then play as normal and should be fine.
