Eagle Files not opening

I'd like to look at the eagle files for the Video Game Shield on this page, but when I download them and try to open them I get an error from Eagle.

Anyone know how to fix this or where else to get the files?

From that web page:
"The Video Game Shield was developed with Kicad..."
