I've experienced much the same problem. I got in touch with the author
but unfortunately he couldn't figure it out either! 
I just gave up which is a pity since it LOOKS pretty good.
Have you tried "Virtual Waves"? It isn't Csound but does lots of high
quality signal generation and processing with an elegant front end.
Type "Synoptic" in your search engine.
