"Protected by Digital Rights Management" Error on E-Reader
I have a Sony PRS-T1 e-reader with Adobe Reader software installed. It is authorized to read DRM content. Using my PC, I download an e-book from library/Freading. The PC version of Digital Editions is able to open the book fine. However, Digital Editions on PC does not recognize the e-reader. As such, I decided to try transferring the epub file (located under Documents/My Digital Editions) to the e-reader manually. However, while I can see the book, attempting to open it generates this error.
I am not sure if this question would be better directed to a Sony forum or not, but I would really appreciate any pointers on the matter. For example, would a compatibility issue between the version of Digital Editions on my PC (4.5) and the presumably significantly older one on the e-reader cause this? Are there any other files aside from the e-pub itself that the device might need to ensure that i have permission to read the book?
I am not really familiar with DRM technology, so I would really appreciate any advice or pointers in the right direction.
