I just re-installed CS3...and now Bridge won't show the CR2 previews...it's just the CR2 icon and when I try to open it up I get a message in CS3 that says "Could not complete your request because it is not the right kind of document." ? I've been using CS3 for the past year and have had no previous problems with this particular issue. The other thing is that when I tried to update Bridge it said that it couldn't complete all the downloads.
Would appreciate the help...I'm getting frustrated
