Registered Users Homepages not converted during install and conversion

I recently installed and converted my previous phpbb system over the phpbb3 RC3. None of the existing users, most of which did have a homepage set, now have a homepage on the new system. The previous version of PHPBB is detailed below and have been 'modified' quite a bit so this may be the reason.
