We'll gladly help, but we need a lot more information about what doesn't work. Can you tell us what you're trying to configure and what is, or isn't, happening. Are you getting any error messages, blank pages, or anything else that would help us understand you're problem?
There's a lot of features in JFBConnect, and once we know which ones you're currently having issues with, we'll gladly help get things going.
Thanks,
Alex
