I have an i-mac with Garageband software. I have just bought a book - Easy Music Projects For Beginners - and have started to follow tutorials.

However, I can't load Apple Loops. Garageband tells me that I have none installed. I've tried reinstalling Mac OSX and Apple Loops for Soundtrack. Both seemed to instal without any problems, but when I try to open Apple Loops I get the message that there are no Apple Loops on my computer, instal the Apple Loops package.

Any ideas?
