I made a very dumb mistake in not backing up the files I deleted in an attempt to downgrade from Airport 3.4 on my PB (which is about to be replaced!) Long story short - I did a clean install of Panther and have now got most software working. I have a Carbon Copy backup on my other drive which contains a perfect install (but is missing some files needed to make Airport function). Now however a number of my programs seem to have forgotton they're registered. I dragged them back from the back-up drive and the preference information to if I could find it. My question is, which files do I need to drage back in order for my programs to know they're registered and where are they all kept? I can't use CCC to rewrite my HD because it's missing the airport files I need. Can this be resolved? Thanks in advance.
