Outlook Express error

[kaper]

Out of nowhere my outlook stopped working. Suddenly I get this error message when I hit send/receive.

One or more messages in your Outbox do not have a valid account specified. Would you like to use your default account to send these messages.

Ive tried removing and adding the account again. Ive tried adding a different email account with the same result. Any idea whats wrong? Like I said, didnt do nothing and it just stopped working.

you have messages in your outbox that need to be sent, if you delete them this message will go away.
