It sounds like you do not provide enough apparent value and hence people do not pay! I am not talking about there "real" value you provide but what value you are able to communicate to those who actually lands on your site. My advice would be to talk to customers, either those who have signed up or alternatively you could go out in the real world, find some target customers and talk to them. This could be in a coffee shop (ask permission from the manager) where you could offer to pay for the persons coffee, then let them use the software and get them talking about what they see, their experience and thoughts - take notes of everything and most importantly shut the f*ck up, do not explain nor complain! Take what you learned and use in your copy writing and development, then go back out again and repeat until you either has proven that people do not get value from what you are building or that they do!
