Cant unzip files

[BumbleBun]

"The archive is either in unknown format or damaged"

I get this message with every single version of the download links.

Or it says its "not a valid archive".

WHAT DO?

I even checked the resolved area, and none of those fixed my issue.

Mine asks me if I want to give it a password.  Is there a password?

You probably got an interrupted/incomplete download.  It's something that will happen if a download server is stressed when a lot of people try to download from it, particularly trying to download the same file.

If you're on Windows, try using the Torrent download.  One of the neat things about torrenting is that it can actually get faster when more people are downloading - downloaders each share a bit of their bandwidth.  I tried the torrent after my .ZIP download failed, and the torrent completed after about 5 minutes.
