I ended up Downloaded ALL my Amazon e-books onto the PW4. Then I Side loaded thru calbre 3500 more. Calibre did NOT tell me that I was adding Duplicates. No Biggie or so I thought. 1st I tried deleting the duplicate... PW4 would Not remove them. I tried to use my PC to delete them...e-books removed but I was left with All the covers. No matter what I tried I could Not get them OFF....ugh. I Took it back to Factory. ugh
Ok so today I re-down loaded just my Amazon e-books. Now I cant get them into collections
