I have been contacted by WotC and asked to remove all of the materials for which they hold the copyright. To this end, the remastered products, which were mostly just reorganized versions of the original rules, have been removed from the site.
While it is possible that they will allow us to post them again in the future, it may not be for some time. In the mean time you can find the originals, as both PDF and print-on-demand products, on DriveThruRPG.
The parts of these rules that were creations of Bill Logan, may return as a stand alone supplement.
