Windows Live Messenger not working? Try this
Folks have been reporting issues signing in to Windows Live Messenger, as in: they can’t. Ed Bott reached out to the Live support team and received a fix, but it does require a registry edit, so by all means be careful. According to Ed, you’ll need to delete the following key:
HKEY_CURRENT_USER\Software\Microsoft\MSNMessenger\Policies
I think I’ll stick with GAIM and Miranda for my IM’ing needs at this point: they’re pretty stable and support chats across IM platforms. Oh, and no registry hacks to make ‘em work!

And least common denominator features too
