I downloaded Adobe Photoshop 6.0 Tryout to work on an art project for school, and did about 2 hours of great work before realizing that I could not save with this trial version. I don't know what to do now, because I really need to save this project and losing all of it and doing it over again later is not an option. No serial numbers that I have found online have worked to register the software, so the only thing I can think of to do is to buy a full version cd and use the info on it to register my trial version....until then I can't even turn my computer off, or I will lose all my work. Please help if you have any ideas!!!
