There is now the Standard Prostitcher which was what everyone had. In January, they released Prostitcher Premium which, when installed, will be a separate program. You can use either one. I was trained on Premium and it is very intuitive. Since they first released it, there is another update to correct a couple of issues. As with any program, there is a learning curve and some glitches. The experts out there are sending in bugs and requests for changes so there will be updates to premium in the future.
