>>Today, when I logged into MSN Messenger, I got a messages asking me whether I want to upgrade to the latest version. I clicked on "no" (option group), followed by the "OK" button, and the login simply aborted. I tried it several times, and it happened over and over again. I could simply not login, until I agreed to download the latest and greatest version!

The latest I had heard (must have been a few weeks ago) is that they would support only versions 5 and 6 - not older versions.

But I had version 6.1; I believe the upgrade is to 6.1.something.
