yes, I think that my problem may be that despite my sansa saying rhapsody and e250r on the back, it may not be an "R".
I read the glossary and it says:
Rhapsody/e200R Models
If the USB options on your player are "MSC" and "MTP" it's non-R, if they're "Rhapsody" and "Plays for Sure" then it's R.
I have the options MSC and MTP options and have been trying to load the "R" files, maybe I'll try the e200's???
My sansa is a Refurb, that may explain the switch
