When I open the soundtrack wizard I get a message of "To be able to create soundtracks, styles are required. Please install extra module 'soundtrack styles'.
I have no idea where this is or why I can't use the wizard. I'm using MEP plus 2013.
I suspect you have the download version of MEP 2013 and have not downloaded/installed the rest of the components which include styles, sound tracks and more effects.
Click Help, Free download a list will appear as shown below, select all the components and download/install them - note the download can take a long while - maybe an hour or more depending on your internet connection.
