Sorry, did a little search but can't help you with those.
Can you remember what kind of content it was? "monsw" is maybe Monica Sweethaert, or "mtv" maybe means "MyTeenVideo" may do a search for these phrases.
My only advise: add the pass to one of the downloaded files, like "monsw-mtv-pc.part1
--pass.rar".
So if you find some files a week later, you can still unpack them (after removing the phrase), sorry for being such a smartass, but that's how i do it
