X1 exported songs have clicks and noises

So far I love X1, it works perfectly for me, at least while getting my hands dirty making the actual music. But when I finish and go to export a .wav file, it does so, but when I listen outside of Sonar, the song is full of cracks and pops, it sounds perfect in sonar. HELP

I'm on windows 7 x64 SP1, using a focusrite saffire 6 usb as my interface. I record in 24-bit 48KHz, and tried exporting in both that and 16-bit 44.1Khz and am having the same results. Also tried to disable fast bounce, still nothing better.
