I had Final Cut Studio 2 and just got FCS 3. I also have Logic Studio 8 and will probably get LS 9 soon. The question I have is that I have already installed Final Cut Pro along with Compressor and such. I skipped Color, Motion, Soundtrack Pro, DVD Studio Pro, and Cinema Tools. But now I need Soundtrack Pro: I went to install it when I noticed that it will skip over Music Loops. I'm guessing I still have that data from FCS 2 or LS 8? Also, I am unsure of what exactly is contained in the Sound Effects install. I'm guessing that just sound effects and no music is contained inside. If I check Music Loops, will it overwrite old data or make a duplicate of existing data?
