SoniVox Wobble Dubstep Grime Generator Help!!!!!

[TawnTron88]

I purchased this for my Protools M Powered 9 a few months ago, and I have it installed and I am able to play it when I open it in the Mix Window. I record enable and try to play along with my songs but nothing plays. I see MIDI notes on the track but no sound. I press one key on my AKAI MPK Mini Keyboard and I get one note but nothing else follows. When I play it back I get absolutely nothing. I have been struggling with this for quite some time and have been asking for advice but all I get are some really vague answers. I am starting to worry that I wasted my money on something I can't get to work. I seriously need help from someone who really knows what they are talking about because I am totally lost. PLEASE HELP ME!
