I am reaching out with all the desperation of a kitten caught in a current! If you are able to download ,extract successfully, and place the B&S Ears and Tails package file in Mods from:
http://black-le.tumblr.com/post/70780708993/acc-b-s-ear-and-tail-male-female
Please share the successful package file!!! I have tried from all others sites that have re-blogged the post, and apparently it worked for them, but not myself. The link will get you to black-le's page where you will see a Christmas post with sims with various ears and tails from Blade and Soul of a cat, bunny, and fox! They are gorgeous and the best ears and tails for sims 3 I have ever found that; so much so that, I have spent more then 7hrs looking for ways to get them. If you can not download them either correctly...CAN SOMEONE PLEASE RECREATE THEM!!! The creator doesn't mind if it is edited or converted. The file name will download as B&S Ear and Tail ACC.zip.
