I converted the ebooks from PDF using Calibre....Yes,they are readable in Reader Library....I also formatted my reader & tried epub books alone & then everything works fine...The moment I add pdf files,the epub files show PAGE ERROR(PLEASE NOTE:THIS DOES NOT HAPPEN WITH EVERY EPUB FILES,ONLY SOME EPUB FILES IN THE READER DISPLAY THIS ERROR).....Then I switched off the device.After switching it ON the files which showed Error Earlier opens without a problem & the files that had no problem earlier comes up with the PAGE ERROR...It is so funny as well as frustrating...

Am I goin wrong somewhere???
