Problem with user contributed clothes

I've been trying to get the following two pieces of clothes to work:
1. http://www.makehumancommunity.org/cloth ... dress.html
2. http://www.makehumancommunity.org/cloth ... othes.html
but I'm getting all kinds of artifacts when putting on the clothing:
I'm also consistently getting the following two error messages when applying the clothing:
1. Problem loading binary mesh: ('compiled file missing: %s', u'C:/Users/Me/Desktop/makehuman-1.1.1-win32/data/clothes/Viking_dress/_dress_fitting.npz')
2. Problem loading binary proxy: ('compiled proxy file missing: %s', u'data/clothes\\Viking_dress\\Viking_dress.mhpxy')
Any ideas?
