After updating my Macbook Pro to 10.8.2 and iphoto 9.4.2, my photo stream has been asking me to log on to my icloud account. Even after logging on, it keeps giving me this message "In order to use Photo Stream, you have to be signed into your iCloud account in System Preferences.''
Kindly assist
PS instructions are here - http://www.apple.com/icloud/setup/
If you have done everything there and have all of the correct versions reset your PS - http://support.apple.com/kb/HT4890

Log out of iCloud in the System/iCloud preference pane and disable Photo Stream in iPhoto's Photo Share preference pane. Then log back in and re-enable, respectively. That should jump start Photo Stream.

photo stream dues not work after updating to 10.8.2
