Is this what you are seeing?
If so this is because you are still signed in in the MobileMe preference pane with your old MobileMe login. Open the MobileMe prefs pane and see whether you can sign out. As MobileMe is now closed you may find you can't do this, so you will need to go through the following performance:
Open your user Library in your Home Folder. Apple have hidden the user’s Library folder to casual viewers, in an attempt to stop new Mac users messing their machines up. To access it, in the Finder go to the ‘Go’ menu and hold down the Option (Alt) key; the Library folder will appear as a choice.
Having opened it, open 'Preferences' then 'ByHost'. Delete all .plist files beginning with com.apple.Dot.Mac or com.apple.idisk. Reboot your Mac.
Now when you open System Preferences>iCloud you should see this:
and you can proceed.
