E_ACT_NOT_READY error

Hi,

I'm on a mac, trying to download a library book to Digital Editions. When I activate the downloaded file I get the E_ACT_NOT_READY error message.

That's one problem. I searched on the internet to find a solution. Someone somewhere suggested erasing the authorisation on my account. When I try to do that it doesn't work: Digital Editions says it's unable to erase authorisation at this time and that I have to try again later.

Thanks for any help,

Best wishes,

Oliver
