I am trying to watch a blu-ray movie with WinDVD 9. I just installed it after reformatting my system. There was some weird intervideo issue during installation but it looked like it installed alright. I open up WinDVD and it loads the disc, then it says the AACS keys need to be updated, so I click yes, and it does nothing. I have tried many times without any luck. I have done it in the past many times, I have had this program on Windows 7 many times. Any ideas? Is there a file I can get to reinstall intervideo, that might be the problem.
