The first time I tried I downloaded them on a computer with Windows XP and it wouldn't unzip the files right. When I tried on a computer with Windows 7 they worked fine though! Just thought I'd let you know.
"I'm still having trouble with the .zip files. I keep getting a message that the compressed (zipped) folder is invalid or corrupted. Not sure what to do at this point. I ordered the Chicago CDs with the album download."
