wasn't able to make it work... it install mostly ok, but have a LOAD of errors i had to correct myself... not all table_prefix are placed in the admin, the legend in the admin is not shown correctly... is a mess in the message admin too, maybe you'd be better to rework it to suite vB3 protocol.

was not able to make the popups work either... you did not used the protocol for templates, globalized, and code structure... looks like coded for vb2...

also, the detect for redirecting to the index.php when not in a popup, desable this, because it'S not detecting in new browsers like safari or mozilla... so that's why many are going to hit the index instead of the real popup...
