Synchronize to continue music subscription

What does that mean?  I received the e250 for Christmas.  I have downloaded 1 book and before it was done, over a week this would display "Synchronize to continue music subscription " instead of playing the book.  Now I have downloaded another book thinking maybe the library had so kind of time limit somehow but the new book does the same thing.  I deleted all the music that came with it already.   I need major help if I ask my daughter to come over and help me again she just gonna  b**ch.     Thank you so much…

You can probably find more help in the e200 series forum.

This forum is for non-sansa stuff…
