How to fix “General error”?

When converting DRM files, the program will open iTunes, Windows Media Player or QuickTime in a separate window, play the DRM file and record the file playback to remove the protection. The program will display “General error” if it fails to open the players.

Please uninstall the program from Control Panel and reinstall the program before the following steps. After installation, please right-click the shortcut for the program, and choose to run the program as Administrator if you are using Windows 7 or Vista.
