Just ignore this. It's a fix for a RL friend that I got from Microsoft, since his MSN Live is all fucked up. (And don't go through the steps unless you want to fuck up your own PC.) This way I don't have to carry around my LJ or Yahoo! password, and I'll have the solution at my fingertips next time I go to his home.
1. Click on Start and Run and type in REGEDIT and hit Enter
2. In the registry editor, click on "HEKY_CURRENT_USER", followed by "Software", followed by "Microsoft", followed by "MSNMessenger", and followed by "Policies".
3. Select the "Policies" key and delete the folder.
4. Restart your machine.
5. Sign into MSN Messenger again.
