Oops, help! After completing the steps I have lost all accounts from the Availability -menu, it is totally blank. The Accounts page lists all my 4 IM accounts. Windows Live has now a name and icon, and I can disable/enable it.

I don't know what went wrong. Selecting "All online" or "All offline" from the Availability page doesn't do anything either . Rebooting doesn't help. Any idea how to fix this?
