Guys (or Gals),
The "nolinking.php" page that you are being directed to contains *all* the relevant information to fix the issue.
As the page explains, the problem is not actually OFPEC, its that your system isn't feeding "referrers" to our system (which is a well-established and valid method for prevent bandwidth leeching).
Read the page thoroughly, you will find what you need to do to fix the problem and resume downloading from OFPEC.
And yes, the Recruitment Depot is still down, but not for long.
