i wouldnt worry about it too much, there are sometimes numerous prerelase beta code versions floating around before a game goes gold. Even if the code is "current" and valid.. they have a month or 2 to change variables and work on securing functions, which will go a lot faster since the bulk of the work is done already.
99% of people getting the code wont know what to do with it anyway..
Hell the homworld code just went public as well.. Totally useless without supportiv files and subsystems.
