I see it's the 2nd file download you say is corrupted and for the second time it looks like the issue is on your side. Sorry pal. I hope you managed to download them, if not I can only wonder if you have your cache cleaned and enough disk space. Closing Unreal Engine, if you have it on, and restarting the browser after clearing the data cache always makes things work. Best luck.
PS: To the leaker of this asset.... thanks for sharing it.
