Right now I’d say don’t rush paying unless you really have to (maybe it goes away on its own somehow), and if it goes further play stupid as much as you can - you found the movie free on the internet and you got it - why wouldn’t you, it was free. Not your fault it was there. And make it seem you don’t understand the concept of seeding, leeching ,etc.
