Garageband .aif not found!

Hi guys I need Heeelp because this is becomeing extreemly frustrating as I have installed GB 6.0.5 (428.5)

on a new system (Lion 10.7.5) and have opened up apiece of work that I did a while ago only to find that some of the instruments

are not there anymore - when the file begins the process of opening, GB a dialoge box comes up to

"skip" or "search" for these following items;

1. Audio file "Orchestra Strings 34.aif" not found!

2. Audio file "Orchestra Strings 77.aif" not found!

3. Audio file "Abstract Atmosphere 007.aif" not found!

4. Audio file "Hip Hop Shaker 01.aif" not found!

I have searched and searched but to no avail - I cannot find these .aif files anywhere.

Now I really don't understand why they are not there because I created the file with these in the first place, I really

need these because I cannot reproduce the work again.

Any help would be massively appreciated.

Chris ;-)
