Share 'Windows Media Center - Movie Unavailable'

Hi Guys!  I am having a HUGE problem with netflix. I like watching it through WMC but I bought a new PC and it keeps saying, no matter what movie I try to play, we apologize - The movie you requested is not available at this time. Is this a known issue? Does anybody know a fix?  I am SOOOO angry about this!  Netflix blames microsoft and microsoft blames netflix. So annoying!!! Thanks!
