After migration assistant, the Photobooth on new MacBook Pro resembles the version from older computer. How do I fix this, and is this indicative of some mistake made during the migration?

I followed the directions for Migration Assistant between my older white Macbook, and my new MacBook Pro. Everything seems pretty much the same on the new computer, except that the version of photobooth on here is no longer the one that it came with (ie the one with the wooden-looking background). It now resembles the one from my older computer. I can't tell if this is the only instance of this, or if there are other applications that have been reverted to the older version. How might I fix this? Should I just restore my new computer to factory settings and start all over?
