Hi Bob,
Not a problem. In 2014 it's easier than it's ever been.
Load in the Realtrack that you are interested in. When the Realtrack is loaded, it must have a line under the name. See the below image. This line says that this RT has a notation file associated with it.

In the above image, the RT on the Piano track has notation associated with it (it is underlined) while RT on the Bass slot does not have notation. (This means that what I describe below will work for the the Piano track RT but not the Bass one.)
When the track is loaded. Generate the song. There's no need for it to play through.
Now simply left-click on the Piano Track and drag it across to the MID quadrant of the Drop Station.

Once it's done, right-click on the Drop Station and you can choose to go to the folder that it's stored in.
Hope this helps,
Noel
