no upload to photo stream
I have Aperture 3.4.1. Before the ugrade to 3.4.1 I used photo stream about 4 times. It worked and installed a series of photos on the cloud. Now after upgrade to 341 it seems I can no longer upload to photo stream. I select a series of photo's. Than select share photo stream. I want to share this so I had the emailaddresses entered. Then the photo selection is moved to the web photo stream. It shows as a new album in photo stream with the given name, but it doesn't show the shared names. Only shared by me. And no photo's are uploaded even after waiting 15 minutes nothing has happened. Checked all the setting in Preferences. Automated up and downloaded is selected, photo stream sharing is selected. So what am I missing?
