Sansa Fuze DRM and Overdrive

I’ve run into an overdrive problem. I listen to overdrive books from the library. I downloaded one, & didn’t finish it before it expired, & wouldn’t play any more, so I deleted it off the player. I have checked it out again, & re-downloaded it, etc, & it still won’t play. Did the “old” license from the first time I checked it out prevent the “new” license from transferring? If so, can I “empty” the licenses on the device & force it to re-acquire a new copy? Is it drmv1pm.lic? How do I handle this file to reset it?
