Whoops: Broken Steel PC is broken [Update]
Update: A Bethesda rep in the UK's just told us that comment's being chased now.
Update 2: The Beth devs are getting the same issue. Thanks, The Reticule.
Update 3: Bethesda's issued a statement.
According to multiple reports, the PC version of Fallout 3 DLC Broken Steel isn't working as it should.
The download throws up the error, "Not a cryptographic message or the cryptographic message is not formatted correctly. (Exception from HRESULT: 0x8009200D)" upon installation.
There also appears to be a difference between the reported file-size (510Mb) and the file you actually click through to download (471.6Mb).
Check EG.
This isn't so great. The Pitt was amazingly broken at launch. We're after comment now.
