Articulate Engage not responding to serial number activation

Hello,

I am working in PowerPoint and wanting to insert an Engage piece into the mix. I click Engage under the Insert menu and the Quizzes and Interactions dialog box appears. Clicking on Engage Interaction in the left hand menu bar, I click "Create New". The attached dialog box appears as if I didn't have the progream - being lead to the Articulte website to purchase it.

Any idea what is happening here?

Thanks,

Ryan
