Query: iListen didn't iHear what iHad to say!

After purchasing the software version 7, I downloaded the upgrade to version 8. No documentation came in the box, one must also download a PDF from their website. Documentation for the latest version was NOT available from their website. After exhaustive hours of training the software with no results, I emailed the company asking for more specific instructions for recognizing WAV files. Over a month later, I still haven't received a response. I found this product to be completely useless.
