...I get finished installing everything except for XLN AD2, which is on a separate installer. I downloaded the files, got halfway through the installation and my computer crashes. I reboot, start installing AD2 again, it crashes again with ominous error messages saying, "Kernel_Data_Inpage_Error" and "Critical_Process_Died".
Now I can't even boot my PC!!!... 
That's a shame. Look on the bright side... at least you were not in the middle of a client session and SONAR crashed losing all that recorded material. That could be a real deal (contract) breaker! But I guess I'm mostly preaching to the choir here.
