This is not a vid-file, its a .rar - a archive, where you must unpack the vid-file from the .rar.
It's nothing wrong with the files. I have downloaded, upacked and played it. It works 100% perfect.
After you have all the .rar files (11) in one map, you can right-click and then click "unpack here" - and your vid-file will unpack in the same map as your .rar files.
