Hello, does anyone know why i get a message saying I haven't got Microsoft Speech 5 installed or suchlike when i try to run the script?  I use that Microsoft Sam thingy for loads of things as I am visually impaired, together with a screenreader for more complicated things.  As the screenreader I use doesnt read Live messenger very well anymore, i was hoping this script would solve the problem but it doesnt really work, hehe probably 'cause i dont have the right software.  I'm confused though as Narator works fine.  Also, if i need to install something different, is it really worth it?  i dont want to screw up anything!!
