I have a Kobo e-reader and have installed Adobe Digital Editions on my PC running Win7 and it all works fine with my Adobe ID. However I also installed ADE on my Macbook Pro (Mountain Lion) and although this is also authorised to the same Adobe ID, I am unable to see any of my purchased books on it. When I check the Authorisation Information on the PC, there is a string of numbers after my email address. On the Mac, there's only the email address.
How can I get my Mac to see my bought books? I tried to de-authorise it using Cmd Shift D (found this by googling) but it didn't do anything at all.
thanks!
