      um.. seems bit tricky!! have you tried rebooting the machine or by configuring with any other MSN account?

        Same as above .. I got the error message 90% of the time .. sometimes, pidgin is able to connect.

        I’m using windows 7. I’ve reinstalled Pidgin rinstallation , and removed my .purple directory.

        just keep hitting reconnect, eventually it will work… it’s been happening for several days now. the first few times i deleted the .com file, but in the last 2 days i just continually hit ‘reconnect’ , sometimes it works after 3-4 tries sometimes 10. but it works every time πŸ™‚

    Removed on Friday, been chatting all weekend, today busy chatting I go AFK for a few minutes and have the same message again: “Unable to validate certificate

    The certificate for could not be validated. The certificate chain presented is invalid.”

    Did the same, deleted and seems to be fine for now, just wander how long until that pops up again.
