I had a similar problem, but with 'windows live' & cured it by doing the following (XP Home SP2 IE6). Give it a try.
'Folder Options' > 'show hidden files'.
Open My Computer > C drive (or whatever letter you use) > Docs & Settings > 'Your Name' Folder > look for a folder called 'NET HOOD'> open Net Hood & there should be a file called 'MyMSN Web'or similar - delete this file, (NOT Print Hood'- leave this alone). Reboot.
