Download 3.9.3?

Hi, I am currently running Catch responsive pro version 3.9.3. I did some tweaks on the theme and maybe (i'm not even sure) in the CSS files. It would've been better if I made a child theme then, but unfortunately I didn't know at the time. So now I'm asking a friend to make a child theme and update the theme, but he needs the original 3.9.3 file to see what I tweaked. Can you provide me with a link to download 3.9.3?
