I need some help.  I have installed, uninstalled and reinstalled Msg Plus Live.  Both times I tried to install it appears to install successfully and get the additional buttons and options but they appear to do nothing when clicked on. 

I don't know if I'm being stupid because I can't seem to work out why nothing appears to work.  All the extra buttons and menus appear and the preferences screen works but thats about it.

Anyone kind enough to shed any light on why this is happening I will be most greatful.

Thanks
