Problem:

After upgrading to the new windows live messenger you find out that you can’t connect to it anymore, no matter what and how you try it simply gives you Error: 80048821. Seeking for help at microsoft using crypt error message only gives you a bunch of useless answers.

Solution:

Despite from the solutions posted on the source link, that didn’t worked for me, i saw a comment on the very same page that said to try the login all in CAPS. That was what fixed the issue.
