Windows Live Messenger version 8.5 is no longer supported by Microsoft, it will prevent you signing in unless you hack around it, which can cause any number of issues.

If you use the latest stable version of WLM 2009 and experience no issues, then there's your answer.

We can't provide support to a hacked version of Messenger as the correct behaviour for it is to prevent you from logging in and so anything else can't be troubleshooted properly
