Hello,
Well the question you asked isn't enough to tell you a precise information.

From your question i can tell that there might be a bug over the site because the date is showing but the link isn't opening, try contacting the helpline over the site, they might help you.
Else provide us with the full information so that we might be able to help you.
Thank you.
