I also have a problem with the file, I tried 3 different machines and 4 different packaging programs.
I always wound up with an "Error 0x8004005: Unspecified error" or "crc failed in encrypted file "Server Dump.zip"".
Also Riffuchs re-send me the file and it's still the same issue.
(I tried: Windows unpacker [Win7/XP], 7zip and the latest WinRar, none of them is able to unpack it)
