Can not burn Bluray Discs? Error

I just upgraded to CS5.5 to CS6. I have never had this problem before. I keep trying to burn a Bluray using Encore CS6, however, i keep getting this maessage after the program tries to burn the Disc: "Bluray Error: "device error", Code: "3", Note "CreateStcSequence:Fail to write M2S file""

Encore will burn the 8.22gb of 8.49gb to disc and then display the aove message. I keep burning coasters, Grrr! How can I resolve this? Thank you.
