Help!! : (

I really need this app! Its exactly what I was looking for, so I purchased it and tried it.... No sound!!! Ive tried everything I can think of and still no sound. So I just wasted hard earned money and theres no way for me to contact the site owner. Every link and address takes to me to a sales page with no option to send an email or report a problem. So im hoping this will work.
I would love for the app to work but if not I would really like a refund... Please
