The security hole on which Aunty reported last week, in the processing of PNG graphic files by MSN Messenger and other Windows programs, has moved Microsoft to require that users of their MSN Messenger upgrade before being allowed back on to the Messenger network.

According to a report on CNET's News.com, on Friday Microsoft began requiring that users download the new, secured version of MSN Messenger, following the announcement by a security company not only of the discovery of the security hole, but of instructions as to how to exploit the vulnerability.

According to a Microsoft spokesperson, "Microsoft was planning on asking Messenger users to upgrade over a longer period of time, but once the security posting went public the company decided to upgrade all users at once".

So, be forewarned, if you want to log in to the MSN Messenger network, you'll need to download the upgrade first. You can download the upgrade here.

I am trying to upgrade and the website keeps telling me it cannot be displayed for 3 days now. I have checked my internet settings and it still shows cannot be displayed. How do I upgrade?

It's true that MSN messager is now only for pay users and others have to use Windows Live Messager? That's what an agent from the technical support by phone told me. So there is no way to still using MSN 7.5?

That sound bogus - I don't think paid versus non-paid has anything to do with
this. (And I know of no paid version of MSN Messenger.)

As far as I know *everyone* has to upgrade. See this newer article:

Sounds like you just have a corrupt download. Try clearing your browser's cache
and downloading again.
