I bought a Sony PRS-600 Ebook Reader for my wife as a present.
On my PC at work I purchased an ebook from Waterstones and downloaded ADE from there.
The PRS-600 was connected to the PC and the book transferred to the reader.
I Gave the reader to my wife and she started to read the book.
She also bought an ebook from Waterstones and downloaded ADE on the PC at home and the book transferred to the reader.
The ebook I originaly purchased usung the works PC is now locked on the reader.
How do I unlock the book?
