Just a warning about how to update. USE A BLANK MEMORY STICK. I used one I had used from a prior year and got some rather odd results (due to a mix of old and new files). Did the update again with a blank stick and all was well. Lesson learned.

No need for new stick. Just delete the old updater files.
