vlc now playing plugin problem

I made research about my problem but I couldn't find any information related that.The problem is: I'm activating vlc portable ''now playing'' plugin from control interfaces settings window, but after that plugin is not working, so I cant show my current song on msn client.What is the problem and how can I solve this problem? Waiting your comments.Thanks for answers.
(note:I can use that plugin with wlm, it works fine)
