Your mileage may vary, but I didn't have any trouble getting it to work. All I did was make sure the FinaleSPBM1A.swf file was in my "templates" folder, and I changed the following line:
<param name="movie" value="C:\Users\Dirk\Documents\The Tournament Director 2\Data\saves\FinaleSPBM1A.swf">
to
<param name="movie" value="<datastore>\templates\FinaleSPBM1A.swf">
Now, there's no reason an absolute path like you originally had shouldn't work, but I can't say if it was correct or not (if the FinaleSPBM1A.swf file was actually in the "C:\Users\Dirk\Documents\The Tournament Director 2\Data\saves" folder). It obviously isn't in that folder on my computer, so I had to change the layout to point to the correct place for me. As soon as I did, it began to work. So short any other info, I'd say make sure the path is correct.
