No problem glad you got it sorted out.
Generally speaking though FTP would be the most likely candidate for invalid/corrupted files. If you download it and can unzip it to a folder on your system it's pretty good indicator the file is good otherwise you should get a CRC error on extraction.
That's why I suggested a different FTP program. There are plenty of freeware and shareware 30 day trials on the web. I love WS_FTP and have used it for years but at times it gets screwy too and uploads files wrong.
Rick says he has in part of the script that it checks to make sure the files are there, but it can't do MD5 or CRC too easily on all of them before proceeding (though that would ensure they are 100% valid OEM or not)
