I can't download the assets specifically in the Falling Leaves Collection

Hi, I tried a few days ago to download the files in the Falling Leaves collection but when I click them I just get this error page and nothing downloads, like the browser is trying to play the file rather than download it. I left it and have just tried again with my first of the 30 daily downloads. When this happens I get the usual popup, saying I’ve used 1/30 downloads and then it jumps to this screen. I tested this by downloading an asset from another collection and it indeed said that was my 2/30, but nothing downloaded or will download from the Falling Leaves collection.

Kind Regards

Dan
