I had the same problem trying to buy tickets on the web site as well. So, I called the Cinema cafe and the staff let me reserve the seats and paid when we got there. It was not sold out either. You might want to call!
Can't really speak to their website issues, but my experience has been that if showtimes are not showing on the website, then they're sold out. You can try calling the cinema for exact Showtime availability.
Make sure you select the date you want first then pick the time.
I had problems as well trying to order tix lastnight i will call them once they open!
Suggest calling the theater
