Thanks for the reply. Yes I have it turned on. The problem is in the iPhoto app. When I click to enable Photo Stream I get a warning that I must be signed into iCloud which I am. At one point I clicked that I did not want to enable Photo Stream and that resulted in the option disappearing so I have to go to iPhoto prefs to select it but with the same message.

Do you also have "My Photo Stream" checked in the "Options..." of the iCloud panel of System Preferences?
(I'm just running through the various places I had checked when I first set up Photo Stream on my Mac. Sorry that I don't recall the order in which I set them. I may never have been in quite your situation.)

I am having the same exact problem with Aperture...as vic999 said I am signed in and yes the "my photo stream" is checked in options..i too tried to sign out but didn't like the warning of losing contacts and other stuff even thorugh it should all come back cause they are still on the Cloud. I have been using it with no problem then all of of sudden I started getting the "you must be signed in". I tried restarting thinking it was just a freaky thing but no help.
