I Lost My Photoshop Elements 7 Installer CD

     Hello Adobe Users.

I've come across a dilemma and didn't know if there was a solution that you could help me with.

I'm not on the adobe website all that much, to not ever on at all but I didn't know where else to turn to.

I'm new to starting this discussion tab, but let me give it a shot.

Recently, I come to realize that my Photoshop Elements 7.0 CD has come up missing after moving; actually, all of my program installing CDs are gone, which were being held all together in one casing. I know Elements 7 is considered a dinosaur for Photoshop, but its my favorite one to use and I know how to use it. And I don't really want to update just yet. But anyways.

Most likely it is probably still here, somewhere, but part of me fears it might of accidentally got thrown away, I am needing to reinstall my Photoshop to another computer.

I still have the serial number if that helps, I stuck it under a tablet of mine so I would never loose it.

But I didn't know what else I should do. Do I have to buy a new one CD? Can I download it for free and use the serial number that I have? Am I only able to download a trail?

Can you help me?
