When I select "Help" in Vegas Pro 9, it thinks for an instant, but nothing happens. Help in 8 works fine (so I've opened it just for help). No errors, just nothing.

I installed the help download, but it's just a pdf? Maybe I have to put it somewhere special?

Mine is a download type license, don't have disks, don't know if that matters.

Can someone tell me how to get help to work in 9?

Thanks
