So recently I upgraded to WLM 2011, only to find that Messenger Plus won't work, where the icon to change settings/etc in WLM doesn't appear :c
I've tried restarting and reinstalling, only to find that nothing will work. It's the latest version of WLM and Messenger Plus, so older versions can't be the problem..
I've been reading in the other threads here that sometimes it's from certain software installed but I don't have anything like that, so what should I do? *can't live without that great chat logging/irc-like command codes/quick texts*
