"Open With..." Shows Two of Each Program

After installing Photoshop 7 and Illustrator 10 on my MBP I had TONS of options under my "Open With" list for images. They kinda bugged me, first off because trying to find what I want in a list of 30 or 40 items is kinda annoying, and second because I knew I would never use any of them. Tonight I decided I'd try to get rid of them. I had previously noticed that they were listed in my applications in AppCleaner, which is what I use to get rid of programs. I decided tonight that I'd back all the files up, then delete them all using AppCleaner. That went fine, except that now when I right click and choose "Open With" there are two of each program. I know, of course that there is only one of each program on my computer. This also happens for non-image files, like there's two Text Edit's when I right click on Word documents. I've attached an example. Does anyone have any idea what I did and how to undo it? I tried restarting and I still get the doubles. I'm wondering if replacing all the files in their original location would be of any help, I have a feeling I'd just end up with two of each of the programs, but 30-40 duplicates instead of the five or six I have now for images.

EDIT: Slight update... I copied over the Photoshop and Image Ready application files from my backup hard drive (and saved my edited files to the backup as well) and after a reboot, I'm back to one of each, but still the long list of stuff I don't and never plan on using. Now I guess I just have to decide if I'd rather put up with two of each program or a crazy number of "Open With" options for images. Any ideas on why the doubling happened so maybe I can get the best of both worlds by doing it right the second time around?
