TedDavidI updated my Sonar X2 with the patch, and it still crashes (blue screen). I'm running Windows 7 64-bit. I think I have the correct audio settings, ASIO, buffer size. The main audio interface is to an M-AudioProjectMix I/O. Only other interface is to an M-Audio MIDI Sport 4X4 to my MIDI hardware modules. It crashes about 75% of the time, and only on exiting Sonar.
