OE6 suddenly rejects my password
 

All of a sudden when I try to access my email, I'm getting a box that says to
enter my user name and password when they're already entered in the box.
When I click OK, or try to re-enter my password, the box just keeps
reappearing. I'm also receiving error message 0x800ccc90 (rejected
password). This is for a POP 3 account which is one of two email accounts I
receive at the same mailbox. I'm receiving email from the other account just
fine. I've read the article Microsoft referred me to but still don't get
what I need to do.
