Intel Mac :: Unable To Move From ModileMe To ICloud?

I have MobileMe installed on my iMac 27.  When I try to switch over to iCloud I get an iCloud window that that has a button that says "Move to iCloud".  When I select the button I'm asked to reenter my passward as though I attempting to use the "Find My iPhone" application.  At the bottom of that window I get a button that says "Open icloud.com".  When I select that button I'm asked to enter by iCloud ID and password.  I enter that information and it puts me in to the "Find My IPhone" application.  When I use the the back arrow I get to a window that has Mail, Contact, Calendar, and Find My iPhone icons.  It appears that everything is setup, but when I exit I have to go through the same process everytime as though it didn't move anything to to the Cloud.  When I select iPhoto and Apperture to turn on PhotoStreaming the system tells me I have to log in to iCloud in system preferences to do this.  I see no way to turn on PhotoStreaming on my iMac.
