Are you struggling to update past 1.11?
That version is really buggy and is pretty much unusable.
All you need to do is log into your account in the forums and inside there, you will find the Mature patch that allows for blood etc. Then dig out your DVD case and on the back of the manual, there is a code that you can enter to access the beta upgrades (they weren't ever officially released, so, this is the only way to get them)
Its really simple once you log in to your serials in the forums.
Hope this helps.
