There are any number of reasons why a zipped file, when de compressed, appears to have nothing in it, or your computer brings up a dialogue box that say this file is empty or corrupted.

I use zip files to transfer my products. While zip files are really convenient, they can sometimes come with issues.  One of the most common issues is corrupted zip files.  When most customers download their files, they are perfectly fine.  But some users, when their file has been downloaded, find their purchased files get corrupted during the download process. This makes it difficult for an average user.

The following link has information that may help you recover your files.

Otherwise, please send me a message.  And I will send the files to you, by email, individually.
