These errors can occur for a number of reasons. The majority of the time it is caused by too many downloads being downloaded at once and/or the download was interrupted.
Follow the steps below to find a fix! (If you're downloading to a mobile device, please read this article)
Redownload; Remove the faulty zip files from your machine and download 1 file from your account. If the file works, continue downloading each file 1 at a time (you may get away with 2-3 concurrently). If the zip file is still faulty follow the next step.
Download archiving software; For windows, I recommend either 7zip or WinZip. These programs can often bypass various .zip file errors. For Mac, I recommend either The Unarchiver or iZip.
