Yaser,
We'll be glad to help out how we can. First, can you please post from the account that you have an active subscription to JFBConnect from? Priority support is for subscribers and supporters of our extension though.
To assist you, it would be very helpful to have the URL of your site so that we can see the styles you're looking for. Once we have that, we should be able to help you get the Login module integrating smoothly pretty quick.
Thanks,
Alex
