OK, that was easy. I used the XML-RPC debugger at [url:fwzht81h]http://gggeek.raprap.it/debugger/[/url] to get the full view of what your server returns. When JoomlaPack Remote tries to login to your site, it calls the getProfiles method. The result I got from your server was:
Fatal error: Class 'JComponentHelper' not found in (path to your site's root)/components/com_jmrphpbb/helper.php on line 1021
This means that the "Blogomunity's p8pbb bridge" you use installed a user plug-in which doesn't work with the XML-RPC calls. Since the problem lies with a third-party extension which doesn't play nice, this can't be worked out at the moment.
I expect to modify plg_jpremote to support user authentication based on the frontend backup's secret word in the next released beta. This would avoid loading user and authentication plug-ins, which seems to be necessary for sites using bridges like this. Alernatively, you could switch off the bridge, but I guess this isn't something you'd probably do.
