Thanks for your offering. I have a bit of house cleaning and rearranging due to my knowing I bought the CS4 software and had installed it and thinking things would work as before I did not realize that by buying and installing another software program Proshow Producer on an external HD and then learning from the company that it had to be on C:/ to work properly. That forced moving other things around, like CS2, CS3 and CS4 and leaving CS on C:/ then reinstalling Producer as CS works fine for the pictures used in Producer and all related files on C: as all my other working photos had to move with the software!! With 5 and a half terabits on 6 external HD's I got careless and did not properly set things set up as I should have in anticipation of my current problem and Adobe's programers, not being mind readers programmed things to look on C: when CS2,3, and 4 lived elsewhere. It's all a mess but I do have my serial numbers and did discover, thanks to your Creative Suite Cleaner Tool offering I found a link to Adobe's original CS4 trial files that I was told by Adobe were no longer available due to CS6 and I can re-download CS4 there and use it since at the moment my CS4 is hiding from me. I think a clean re-installation should work before running the 'cleaner' with its' gottchas. I shall send a later follw up when things are successfully reloaded. If you think of anything else of value, I would certainly appreciate your knowledge!
