I've had some offline discussions which lead me to calling the office. I, too, was having problems...couldn't get past the first screen. The interface screen needs some work...they're getting to that. There are some entries that are mandatory, but of course, the screen doesn't say that. Be sure you fill in every blank, although the website and pictures don't really need to be completed. Be sure there's a price...it needs a number...you don't need a $ or anything...just put in 100 or 5 or whatever. I did all that and it accepted my initial input and I moved to the next screen.
So, be sure you fill everything that's critical in. Even the keyword. Hopefully, they'll adjust the interface so that it will highlight something in red that needs fixing.
Let us know if you're successful or still have some problems.
