Nope, you not need an additional program.
Try with this:
1. Close JD2 (If is running)
2. Backup the folder plugins which is into the folder cfg (...JDownloader2\cfg\plugins)
3. Delete the original folder "plugins"
4. Start JD2, and check If JD2 returns the audio files. Notice you will have to set your settings again, because when you delete the folder "plugins" JD2 will use the default settings.
