I've pulled you up in the system, and it appears you did have an "Adrian Jarrell-PreviewUser" account, though I believe that is on the Blackboard Administrators side. Meaning, a different blackboard ID than your regular Instructor Access.
I recommend reaching out to your Blackboard Admin to see if this is something they can assist you with, if they can't, please reach out to your WileyPLUS Account Manager or Implementation Specialist to assist.

Clarification: I'm sorry Adrian, this "PreviewUser" is generated when you access WileyPLUS in the student view of Blackboard. Again, something you may have to talk to your Blackboard Admin about. - Tom
Yeah, that user is a weird one. I don't know why our BB administrators put that one in there... I guess they did that.
The problem was in Wiley, not in BlackBoard. It was resolved a few days ago. I received a frantic email from a procrastinating student last night (with screen shots) and I assumed the guest access link had again been disabled. Turns out it's still active and the screen shots were from last week some time.
Thanks for the response.
