I'm having some problems getting Live Messenger to work on the RTM build. I have installed it and when I try to connect I get the error message: We can't sign you into Windows Live Messenger Signing into Windows Live Messenger failed because the service is temporarily unavailable. Please try again later. Error Code: 80040154 I wanted to try uninstalling it and reinstalling it, however, it doesn't appear in the add/remove programs list and if I simply locate the folder and delete it, it reappears when I restart. Has anybody got any ideas as to how I resolve this? Cheers.
