Here's some important things to try. This is a specific list compiled from Microsoft resources for your issue One of these solutions will hopefully solve your issue.
Unable to login to Messenger - Security Upgrade Required
As part of Microsoft’s Trustworthy Computing initiative, Microsoft is providing a security update to the .NET Messenger Service which will require an update for some MSN Messenger or Windows Messenger users.
If you have not completed the update, you will be unable to login. To complete your update Please Click Here
1. The date on your computer needs to be set properly -- double click the clock verify that the time and date are set.
2. If your password information is not saved, verify that you are typing it in with the correct case (uppercase or lowercase).
3. Change your password @ http://memberservicesnet.passport.com/, then try signing in again.
4. If you use a firewall (like ZoneAlarm, Norton Internet Security etc. ), it's possible that Messenger doesn't have the correct rights to access the Internet, especially since you upgraded. You may need to re/add Messenger to the allowed list of programs in your firewall if this is the case.
5. If you disabled your firewall in the past, it still may be blocking Messenger -- try
restarting it and see if that helps the situation. You also might try uninstalling an
installed firewall, to verify that it isn't causing a problem (even if it is disabled).
6. Clear your IE cache and cookies -- open Internet Explorer, click the Tools menu, then Internet Options, then click the Delete Files button, and when that's complete click the Delete Cookies button.
7. Check your IE Security settings -- open Internet Explorer, click the Tools menu, then Internet Options, then Advanced tab, scroll to the Security section, and verify that "Check for server certificate revocation" is unchecked. Also verify that 'Use SSL 2.0' and Use SSL 3.0' is checked, then click OK.
8. Click Start, then Run, and enter the following: regsvr32 softpub.dll then click OK
Then try again & let me know how this works for you 
just because this is related, ill also add some information from CJ Barone. (i know its posted elsewhere, but its hard to find
)

I had this problem... But I found it out! The solution lies in the registry
1) Start->Run->Type REGEDIT and press [enter] -> On the left hand panel, navigate to HKEY_CRRENT_USER -> Software -> Microsoft -> MSNMessenger
2) In the right hand panel, Delete the DAConfigVersion and DomainAuthority values
3) Restart MSN, and it WILL work!
Thats all for now
