I've messed up the Butte upgrade to 1.2

I have downloaded the upgrade twice and get the same results both times.
I get piles and piles of what look like road signs (they have a black and yellow striped border around a white sign that seems to have the letttering backwards)
I don't know how to do a screen shot to show you what I'm getting But I'm hoping someone knows what I've done wrong.
Any ideas?
Dave
