Easy to install and set up, all the options I could have wanted and looked great on the page but after one day it just stopped working. There's just a blank space where the fanbox should be. There's absolutely no support on the website, no forum, no documentation and no FAQ and you have to pay to contact the developer. If it works it's great, if it doesn't your out of luck.
Sorry to hear you had problems.
Facebook recently done some changes to their API and I also experienced problems. Facebook have now changed the Become a Fan button to Like button and few other things. If you still having problem then please contact me on my website.
I am working on to setup forum but not ready yet.
