I have MSN as my main service provider and i have msn messenger 6.2. When i downloaded Messenger Plus my messenger would no longer work. I would sign into MSN and could acces my email and surf the net but my messenger would not even respond to me trying to sign in. I even tried reseting my computer and it still didnt work. I dont know what to do with it now
Try uninstalling Messenger Plus! and try again.
It seems unlikely that the behaviour you're describing is being caused by Messenger Plus!. Uninstall it to make sure
