Netlibrary - Overdrive

[pmf]

New to this.  Sorry if these questions have already been answered.  I checked and found nothing.
Just put Rockbox on a Sansa Clip and on a Sansa Fuse.  Now, cannot get my netlibrary overdrive books to play, even if I start the player in original software mode (holding left arrow while turning it on).  Is there a way to restore the players to the original status, that is, unrockboxed?  Or, better, is there a way to play overdrive books using Rockbox.  Or, a little better, can I keep the Rockbox on the player, open the player using the original software and play overdrive books?

Is there a way to restore the players to the original status, that is, unrockboxed?

Yes, by following the uninstall directions in the manual.  If that doesn't fix playback, please let us know.

  Or, better, is there a way to play overdrive books using Rockbox.

I don't know what overdrive is, but if its one of the formats we support, then yes it should play.  If its not, then no it will not.

Thank you for the quick response.  Overdrive Media Console is the program I use to download Netllibrary audiobooks from my publc library.  I believe these audiobooks are availabe for download from most public libraries in the U.S.   I was hoping that I could use Rockbox to speed up the readings without affecting the pitch.  Rockbox does this well for other books (non Netlibrary-Overdrive) I have on my player.

It sounds like a DRM system. 

There is this note in the manual:

DRM capability.
    It is possible that installation of the bootloader may lead to you permanently losing the ability to playback files with DRM.

I don't know whether or not this is actually the case for either of those players.
