Query: Can't connect to PC

Picture is beautifull, but cannot connect to my PC via Firewire port, Windows looks for a AV/C Subunit software nowhere to be found, Canon tech support unable to help. Looked on various forums in the internet and this seems to be a common problem, with no solution so far.Nobody seems to know what is AV/C Subunit
