I just uninstalled my messenger because the plus did not show up on the messenger 8. I reinstalled it again and the plus live and still nothing what the hell am I doing wrong and how do I fix that?
One other big reason found so far for all these problems: having an old (or recent) Smiley Central DLL if your Messenger directory. Uninstalling Messenger will not remove this file.
After uninstall Windows Live Messenger, make sure to delete "C:\Program Files\MSN Messenger"before reinstalling, this has been proven to fix many problems from people emailing me.
