E_ADEPT_NO_FULFILLMENT_RESULT

Hi,

I have a customer who's trying to download her ebook in ePub format on a Mac.

After helping her with another license error. Now she's getting this one:

"Error getting license. License server communication problem. E_ADEPT_NO_FULFILLMENT_RESULT"

I don't think I have come across to this one before.

Any suggestions?

Much appreciated.
