I was having a problem with several styles that I was sure I had, still having N/A behind the name. They would show in my style picker but would not load so I went back and checked my downloads and sure enough they had been downloaded but somehow never installed. Just double clicked on them in the downloads and they promptly installed. I had to run the style picker to update and we were back in business. Could this be a cause of the problem you are having?
