Torrent cannot be archived. Save button disabled

I have a Pro account and was trying to download a 5.87 GB torrent. It downloaded into boxopus okay, however, I can not save it using the "Save" button (disabled) or click on it's link to download it. Checking the link in  it's source it says Sorry, this torrent cannot be archived. 

I can save the torrent by downloading it's constituent files, but was asking if this could be fixed. Or a way to download them as a folder instead of each file.
