Cant Print Shipping Return Label - eBay doesn´t permit it - Publication Eliminated!

[baetrade]

I bought an item and when I tested it it didn´t work. I communicated it to the seller and he suggested me to return the item and that he would pay for the shipping. When I tried to print the label for the return, there was a malfunction in Ebay since it showed as if I had already printed it but I actually hadn´t. It did not allow me to do this. I also noticed that the publication was eliminated on Ebay. You can see the picture to understand. 

Ebay is requiring me to provide a shipping return track number, but I´m not supposed to pay for it if the product malfunctions. 

What can I do to get the buyer to return my money?
