Hello there Cynthiawgalloway

Do not worry. Your problem can be resolved. Error 40402 occurs when Yahoo server detects that the user of Yahoo Messenger is doing something which is not according to the sequence and this is what triggers the error. 
For solving this, try to edit the details of your contacts in your address book before editing messenger contact information. If the problem persists, try fixing it from your web profile account. You are also recommended to update to the latest version of Yahoo Messenger that is, Yahoo! Messenger 11.5.
Hope your problem gets solved soon. Best of Luck!
