I cant tell, but there are points when the site just simply kills itself for my browser and says the file is hidden, or invalid file name.. This upsets me because I really wanted to try these mods and they looked good but it seems I cant get a hold of them. Just refresh until you get it to work, it happens. Since Dawnguard just came out, the website traffic is a bit glitchy, just be patient and refresh and try different download servers.
