Missing Extras

I recently picked up SE:V Bonus Edition and installed it all on the laptop. When SE:IV is launched, I get a menu with Extras. Clicking on that I get a txt file telling me to look in the Extras directory on the CD for bonus material.

Only there is no directory on the CD. In fact, there's only three files on the CD: autorun, an SE:V icon and the setup file.

So where are the extras?
