I am unable to send or receive messages from Live. error 4202, a newer version of live is available you must install to continue. I put no and yes, rebooted and it still comes up every time.When I try to send questions to you it says kill pages or wait, neither works. Help!
Don, Error 4202 refers specifically to invalid characters in an address.
Invalid characters include :
![]()
Check your Outbox to see if there might be an unsent message with an invalid character in the address causing the error. If you find one, delete it.

Hope that helps.

Hi Cynthia,
Thanks for the explanation. I’m annoyed to see such error messages that offer no help/explanation. It’s high time MS & Others come up with error messages that also explain the action needed from users to solve problems. This would also significantly increase the user satisfaction and avoid many of our online complaints and rant.
