i remember when i downloaded CS3, i had a trial version executable file and the instructions in the notes said to alter the ".exe" file extension to ".xx" in order to confuse the 30-day trial into becoming a fully functioning peice of software.
more like freeware, haha!
i then uninstalled it because i preferred the simplicity of photoshop elements. i cant see myself using advanced photo editing software unless i have a lot of free time on my hands.
