After effects CS6 3D Camera Tracker

Each time I try to use this feature After Effects hangs on the 'initializing' phase and never actually applies it. This is strange as well because the exact same thing happens with warp stabilization and I had the same issue which I was unable to resolve in CS5.5.

Warp stabilization works for me in Premiere Pro for some reason so this is not too much of an issue for me.

Has anyone else had a similar experience? Any suggestions to solve the problem would be greatly appreciated

Thanks
