Yep. I had to do the same for CS5. I own the suite and have the discs but can't install them on ODless Mac. Adobe will not concert disc purchases to DL purchases even with verified and registered productsThey don't have CS4 anywhere on their site anymore. Am I going to have to torrent this?
Edit: Extremely disappointing, I commented to my wife that it would be easier to DL and install a cracked version of CS 6 ultimate than to reinstall the purchased version of CS5 with the discs sitting in front of me.
