Mac - Bad device Key error when opening books - Ideas?

[AndiRob]

I have tried:

1) Updating to latest version

2) De-authorising and then reauthorising

3) Ensuring password is alphanumeric by changing my password

4) Removing the "activation.dat" file from the DE folder (closing down ADE prior to removing and then opening after file deletion)

Any other ideas on this?

Thanks - Andi
