I don't want to be a shill for this software, but the guy did make a
nice presentation and it seems like it would solve the problem.
Also, I think the software is 'free' in the 'free speach' sense. But
he does charge for a book of documentation. Since, I've never used the
software, I can't say what your chances of getting it working are, if
all you have is the setup screens. The impression he gave was that you
can get it working with just the screens, but to tune it well, to your
situation, you will benefit from the book. 

And, since I've never used it, I may be wrong as to its usefulness.
