Sorry I'm posting that here since I can't post elsewhere...
So these files can't be found in the download section:
https://arteria3d.myshopify.com/collections/uma/products/tudor-squire-lady
https://arteria3d.myshopify.com/collections/uma/products/medieval-assasin
And also FYI I think the video is on the wrong page here: https://arteria3d.myshopify.com/collections/uma/products/swimwear-set-for-unity-uma-jane
