I feel like I am having such a hard time learning all the basics of photography. ::sigh:: It's making me feel like giving up. Ok, vent over. I am trying to download adobe DNG converter so I can open camera raw photos in my PS/CS2 but that's not working either. It looks like 5.4 is an update but as I try to download its giving me an error message saying "installer integrity check has failed. common causes include incomplete download and damaged media. contact the installers autor to obtain a new copy." So, I am guessing I have to upgrade to CS4 to get this update? I just don't know.
