Nuendo 6.06 Crashing at Initialising:AAFFilter

Hi i have an issue with Nuendo 6 crashing at Initialising: AAFFilter.

I recently installed PLAY 4 for EWQL and for that Nuendo was crashing at AAF Filter. I upgraded both Nuendo 6 to Nuendo 6.06 and Play 4 to the latest 4.023 but still no luck. Read people on this forum having issues with PLAY 4 so i uninstalled it but Nuendo is still crashing at AAFFilter.

What is the AAFFilter and how can i reset/fix this problem?

Any help greatly appreciated.
