[bitfolk] Apt-get update 403

Hi, This is my first time posting on this list so be gentle! I run Debian Lenny on my VPS, and have recently added lenny-backports to my /etc/apt/sources.list in order to get the latest version of Mercurial, as a repository I'm working on couldn't be used by the version on Lenny. This was a few weeks ago, and apt-get update worked fine then I think. Now I am getting a 403 when running update: $ sudo apt-get update Hit http://www.backports.org lenny-backports Release.gpg Ign http://www.backports.org lenny-backports/main Translation-en_GB Ign http://www.backports.org lenny-backports/contrib Translation-en_GB Ign http://www.backports.org lenny-backports/non-free Translation-en_GB Hit http://www.backports.org lenny-backports Release Hit http://www.backports.org lenny-backports/main Packages/DiffIndex Hit http://www.backports.org lenny-backports/contrib Packages/DiffIndex Hit http://www.backports.org lenny-backports/non-free Packages/DiffIndex Hit http://apt-cacher.lon.bitfolk.com lenny Release.gpg Ign http://apt-cacher.lon.bitfolk.com lenny/main Translation-en_GB Ign http://apt-cacher.lon.bitfolk.com lenny/contrib Translation-en_GB Ign http://apt-cacher.lon.bitfolk.com lenny-backports Release.gpg Ign http://apt-cacher.lon.bitfolk.com lenny-backports/main Translation-en_GB Hit http://apt-cacher.lon.bitfolk.com lenny/updates Release.gpg Ign http://apt-cacher.lon.bitfolk.com lenny/updates/main Translation-en_GB Ign http://apt-cacher.lon.bitfolk.com lenny/updates/contrib Translation-en_GB Hit http://apt-cacher.lon.bitfolk.com lenny Release Ign http://apt-cacher.lon.bitfolk.com lenny-backports Release Hit http://apt-cacher.lon.bitfolk.com lenny/updates Release Ign http://apt-cacher.lon.bitfolk.com lenny-backports/main Packages/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/main Packages/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/contrib Packages/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/main Sources/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/contrib Sources/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/updates/main Packages/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny/updates/contrib Packages/DiffIndex Ign http://apt-cacher.lon.bitfolk.com lenny-backports/main Packages Hit http://apt-cacher.lon.bitfolk.com lenny/main Packages Hit http://apt-cacher.lon.bitfolk.com lenny/contrib Packages Hit http://apt-cacher.lon.bitfolk.com lenny/main Sources Hit http://apt-cacher.lon.bitfolk.com lenny/contrib Sources Hit http://apt-cacher.lon.bitfolk.com lenny/updates/main Packages Hit http://apt-cacher.lon.bitfolk.com lenny/updates/contrib Packages Ign http://apt-cacher.lon.bitfolk.com lenny-backports/main Packages Err http://apt-cacher.lon.bitfolk.com lenny-backports/main Packages 403 Sorry, not allowed to fetch that type of file: Packages W: Failed to fetch http://apt-cacher.lon.bitfolk.com/debian/ftp.uk.debian.org/debian-backports… 403 Sorry, not allowed to fetch that type of file: Packages E: Some index files failed to download, they have been ignored, or old ones used instead.
