Have you tried logging into the Cakewalk Web site first  (with the same credentials you use in CCC) and then clicking on that link?
 
If I do so, I land up on a page listing my problem reports.

The reports above do not appear in my problem reports list. According to Noel's explanation above, expired users seem to count as demo users, so those reports get orphaned. And apparently nobody is interested in fixing that because crash reports from people who aren't still paying them don't seem important.

As a matter of interest, if you use the Cakewalk Problem Report Form to add a report while you are logged in, does it show up in your list?
