Plex Client not working with Netfilx

Hello everyone,
I am having trouble using Netflix through Client. I installed the plug-in, gave it my password, and accepted the cookie. When I select Netflix it signs me in and I can browse, search, see my queue, and select movies for streaming. When I select the movie, I get the little pop-up telling me to wait a moment, then I get the familiar screen with the circle of blue dots as the movie loads. I then get the following error message: "Internet connection problem Error Code NB106-152. It then tells me that I have an internet connection problem preventing playback. The internet is connected and I can access Netflix just fine using my browser. I'm not sure where to go from here, any suggestions?

Thanks for the help. Silverlight is the current version, tried reinstalling, and flash is version 11. I tried installing Flash 10.1. Still the same error. I will see if I can find an earler version that will run 64 bit. I'm not using a Mac TV, but a Mac Mini and I like the idea of doing everything through the Plex interface.
