All the N.A. site says is that missing parts will be downloaded as soon as possible, its been like that for some time, they also say they are going to produce a list of missing parts, but I have never seen one. The only reason I know, about it, was when I was doing my own research and on a visit to N.A. I found what I was looking for and it was not on the website. When I asked why, they said it would be downloaded and that was almost 2 years ago.
I don't know if others on rootschat have had the same problem, it would be interesting to know.
