Welcome to Subsim matey
I think the update that is being refered to is an update for the Starforce drivers. I'll try to find a link for you.........
You may not know that even if you remove the SF drivers, they are automatically reinstalled when you run SH3 using the disk.
Maintain depth and I'll be right back.
FYI - have you read the SH3 & Vista sticky at the top of the page?
