I changed my MobileMe account. Numbers is still using the old account information when I try to copy to iDisk and will not let me change them. How do I reset the MobileMe login for iDisk in Numbers?
I get an error message popup and cannot tap the sign out fast enough. That option is greyed out while the popup is active and the sign out option disappears when I tap OK. I finally ended up deleting the Numbers app and then restoring it via iTunes.
