What it means this message? It means i can get what i want, right?

No, seriously, i can't find an explanation. If there's someone who can indicate me where to look, would be helpful for me, thanks.

It means what it says. The NZB is no longer available, and its thread on the archive here is only kept for reference purposes. You'll have to look for it elsewhere.
