Hi, GenieDC.

Judging from the log, the 2005 World Book Reference Suite looks damaged -- specifically, there are a series of symlink/aliases in there that seem to be broken, which means it's *probably* unlikely to work (at least, the whole "SMKAppKit.framework" looks to be pretty busted, but -- not being the author -- I don't know what that is).

So -- what I'd do is, indeed, remove it. You should be able to reinstall it from your Software DVD pretty easily -- Apple's been very good about that kind of thing recently, but check FIRST: it should say something about restoring Software when you insert the DVD that came with the system. (Don't boot from it -- that shouldn't be necessary.)

Regarding "disk image concept" being confusing -- with a bit more direction as to what you're finding confusing, I'll try to fill in the gaps...
