iCloud Mail doesn't load, but all other iCloud services work fine I've been having this weird problem with iCloud for a while.

If I go to icloud.com, I can login just fine, and everything works (Contacts, Calendars, etc.), EXCEPT the Mail app. Whenever I click the Mail Icon, I get this error:



When I click "Report to Apple" it gives a more detailed log, ending with this message:

Sat, 24 Dec 2011 04:13:07 GMT:  ERROR: CoreMail handled error 13002 before exiting Mail


Anybody know how to fix this?

By the way, whenever I try to login to Mail in the Mac OS X Mail.app or the iPhone mail, I get The iCloud IMAP server “p06-imap.mail.me.com” rejected the password for user “myusernamehere”
, even though the password is correct.
It seems it was a temporary problem, as it now appears fixed.
