Well how you couldn't tell it was nulled is beyond me. I mean, the included info file says the name of the release group right in the filename, the file they were giving you isn't legally free (a quick glance at their website would've told you that), and just to ram it home, the info file actually says "nullified by" right in it.
This is a zero tolerance permanent suspension for a confirmed violation of our warez policy for uploading illegally obtained pay-to-play software onto our server. You will not be unsuspended or provided access to your account for any reason, including to get fresh backups. Good day.
