The set up and domain looks good. Your layout looks clean and professional.
Just focus on making new topics. I know it can be hard from time to time because we all run out of ideas on what to post. If you really want your forum to work. You've got to make time. Eventually you'll get a member or two that will start posting new topics.
Other than that I think your primary problem, as is with most forum owners, is getting and keeping active members.
