You may need to import them into iTunes for the program to see them. Did you download the files on your iPod touch? If so you may have to tell iTunes to download the files into iTunes.
This has happened to me before. The files didn't copy over when I sysinced the device. I hope this helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
