Crash in Sonar 8 under Windows 7? What the ...

So I was editing some long and painful audio program on Sonar 8 under Windows 7, and TWICE I got the bluescreen of death. However, this is the first time I experience this. And seriosuly I don't know if I should blame Windows 7 RC1, or blame Sonar 8, or even blame the Firewire Solo driver.

So I just set up the auto save, and .... continue finishing my work :-I .
