We would need to review your installation in order to see what is happening. As mentioned by my colleague, this is an old bug which has been resolved so we need to why it is still impacting you if you're on the latest release.
We would need to look further into this for you, however the access details on file appear to be incorrect or missing. Could you please update these details by visiting your client area, selecting the relevant purchase, then clicking "Review/Update Access Information" under the "Stored Access Information" section.
We look forward to further assisting you.
