Hi,
Did you use this site to redeem the product key? https://setup.office.com/redeem/enter-key
Where did you purchase the license? Was it directly from Microsoft or from a third party?
Try opening an InPrivate window (Ctrl + Shift + N) in your browser, then try redeeming the product key again. Does it work there?
