Hi, I have a Sony VAIO VGN-AR51M and it plays most bluray dvds. When i load up WinDVD BD it comes up with the message 'The AACS Key has expired. You may not be able to play back some titles. Gamegain Serial Key. Press 'Yes' to update.'

If i press yes it signs me into to correl and comes up with an error message saying 'Error Code: R03-Explanation:Cannot find matching AACS Key or patch.' If i press no to the update it lets me play most movies such as 'BLACK HAWK DOWN' AND '300' but wont let me play a new dvd (Green street 2) and says 'WinDVD stops plaback because of AACS error check' and goes to a blank screen. I have downloaded all available updates from Sony. Please can anyone help? Greatly appreciated.

Please can nobody tell me to by other software.Thank you. Hi Mark, Version 8.0 DXVA B09.670 of Win DVD is the latest version of Win DVD for your Vaio. All I can suggest is that you contact Sony Vaio support and ask if a newer version of win DVD is available for your Vaio, you can do this either by phone or via e-mail, use the following link to find the contact details: [url=Unfortunately I expect you'll be requested to perform a system recovery to resolve the AASC key being expired.
