problems with iPod files

[assampedas]

Yesterday I was downloading the iPod files for most of the lessons, and encountered a couple of problems:

1) some of the zip files produced a WinZip error message saying the file was not a valid archive;

2) after loading all the notes & sound files into my iPod mini, the line by line audio only worked with certain lessons and not others, even though I had uploaded all the audio files.

Wonder if anyone can help me out here.

Thanks very much.
