Wait, you feel down the stairs, as in feeling down the dumps because of the winter blues, or fell down the stairs because they were wet? The feel confused me. Either way it sounds bad. Don't feel down!

Do you have a version of Photoshop now? Adobe gave up some serials for CS2 recently, along with a link to the CS2 Creative Suite if you want everything and not just Photoshop. It's not supported, and since they're older sometimes they won't run on newer systems, but IT'S FREE AND TOTALLY LEGIT.

FWIW one of my fave concept artists Feng Zhu had been using CS3 to do his Hollywood film work until about four months ago. I guess if it works, it works.
