Broken Steel bugs

Bugs and glitches/exploits in the Fallout 3 DLC pack Broken Steel.

Installation bug: May 5th 2009 PC release downloads via Microsoft Games for Windows Live. Upon completion of download in the G4WL client a message may read: "Install of item Broken Steel failed. Not a cryptographic message or the cryptographic message is not formatted correctly. (Exception from HRESULT: 0x8009200D)" This will happen after repeated downloads and the 'retry' button on the G4WL client will not work. Upon investigation of the DLC files themselves (located in C:\Documents and Settings\user\Local Settings\Application Data\Microsoft\GFWLive\Downloads the winrar archive containing the DLC is corrupt and will not extract with Winrar or 7z. Note that this renders the whole DLC unusable. No known fix at this point.
