Facebook connect and like box widgets are not working

Dear Administrator,

I just purchased Ultimate Facebook few days ago and I already activated the settings (successfully connected). I can use Facebook album widget but I cannot trigger Facebook Connect and Like Box widgets in the frontage. Please kindly advise whether I need to activate any other user login/registration plugin in order to do so, please also suggest any compatible login/registration plugin.

My new website being developed is:

Thanks a lot,

Michael
