Alex,
I just happened to come across this thread. I realize my subscription is not active right now. It happened to lapse on the very day I started having issues. We are a development site who is using both JFBConnect and JReviews and also having issues with the 404 on the links. To be honest, after this problem, I've been thinking about trying another route, but decided to come here and try after doing some more research to see if you could make it right. I don't know if you have another development site you've been trying, but you are welcome to try mine, if needed. If it works, we will definitely renew our subscription, but we cannot afford on putting more money out on an extension that currently doesn't work for what we need.
