your server delivers many incomplete downloads. Especially greater files do not arrive completely. The download is interrupted after 80-90%. Maybe some faulty dds files are causing this?
A corrupt file inside a zip should not cause that. It can be a hiccup from the server or something else. Often it helps to clear the cache and then try again. That have solved most problems like this.
