Ah, awesome! Thank you very much.
I actually thought of downloading the trial versions of Photoshop and Illustrator, but I ran into an annoying problem.
Part of the files I installed was my user settings, and so the Installer for the trial versions keeps finding the database file from the original CS3 install and tells me that I have to use "the original installer," aka, the disc.
If only Adobe offered a demo version of CS3 Design Standard, then I would likely be able to download it and install with no problem.
