Adobe Digital Edition 3 - Sharing e-books between devices

Hi Everyone

Does any body know how to tackle the captioned issue ?

Currently , I have ebooks installed on 2 laptop.

One is Lenoval T440p. The other is AusT100TA-D007H (transformer) which is more like a tablet with detachable keyboard. I installed Adobe Digital Edition 3 on both devices with different email accounts registration.

The Adobe online consultant told me that i can group them into account by deauthorizing one of them a by pressing Crtl+Shift+D nd then uploading the material to the main account by pressing Crtl+Shift+E so that both devices can be linked.

After all, I find that it does not work.

Can some body help pls ?

Regards
