Hello in the derived product I did not find the XML to download it, look in other pages and create one myself.
This is the link of the product I want to derive.
https://es.imvu.com/shop/product.php?products_id=22476413
This is the XML that I create as I found it to say

I don't know what is wrong because where I found it said that I had to copy the link before the .MP3 anyway I tried to copy it whole and it did not work for me
