I uninstalled nis 2009 from 3 different computers in my house, and now zune market place will not connect to internet. That program did before and now it doesn't. I brought my laptop home ( which did not have nis 2009 installed) thinking maybe problem with marketplace, but it works perfectly on my laptop. So its not Zune marketplace, or the internet connection. Nis 2009 must have changed something and now I cant use Zune marketplace. I also uninstalled zune marketplace and reinstalled and its the same problem, I called zune and they have no idea whats wrong, they said it has to do with my computer to which I agree. Anyone have this problem? The only way I can acess zune marketplace is to go into my router settings and put my ip address under the DMZ mode
