Go to the Product Support page, then select the ProTools version (in this case, 6.9). 6.9 isn't available in the dropdown menu, but if you go to the bottom of the page and click "P-T" it'll show. Then, just hit "Downloads" and it'll be there.
You can also choose your Pro Tools hardware system from the top of the page, then Downloads. The Pro Tools LE 6.9 update is on the second page of the Digi 002 downloads, for instance: We will be adding a Pro Tools 6 downloads section as well to make those easier to get to, like the Pro Tools 7 Info link on the right side of the Support section.
