I've run the bonus pack add on, but I'm not sure what it actually adds so I'm not sure it worked.

The reason I'm not positive it worked is after I click "Finish" in the final install dialog, the installer process hangs out forever in my process list. The GUI for it closes, but the process never goes away. Makes me wonder if the install finished or not, which brought me to the question of "what's in the add on?".
