You should be able to see both older uploads like original photosynths from the Windows desktop application as well as panoramas from Microsoft ICE, or Photosynth's current mobile panorama apps in addition to any new Photosynth 2 photosynths from the Technical Preview on your profile page here on the old site: http://photosynth.net/userprofilepage.aspx?user=friedrichs
If all you want to see is your new Photosynth 2 content, you can see your profile on the Photosynth 2 beta site here: http://photosynth.net/preview/users/friedrichs
I can see plenty of uploads on your profile, so if you're not able to, perhaps a web browser extension or toolbar is interfering with the rendering of the page?
If you could take some screenshots of what you're seeing or take a quick video with your phone of your empty profile page and upload it to a public OneDrive folder or something, maybe someone can help you figure out what the problem is.
Your fellow user,
