RED AMA v 1.9 doesn't work?

Hello All,

I've just upgraded to Media Composer 7, and when I download the RED AMA 1.9 plugin from Avid's site, it has no extension. And if I try to unarchive it, I get gibberish. If I add a .zip extension, it still gives me gibberish. If I add it to the AMA plugin folder it doesn't work.

Anybody know the secret here?
