[Plugin: Facebook Comments for WordPress] Not working anymore after update

Graham After the update, I desperately have tried for the last 2 days to get it running again. All worked fine until just before the update. Now I am lost. So dissapointed because I really liked it. Have gone through all your suggestions below. Uninstalled, installed it again…whatever I do, It just doesn’t work.
