I Can't Find My Audio + MIDI Library!

 
I recently upgraded from SONAR 6 LE to SONAR X1 Studio.  I am working my way through some of the tutorials, specifically, the one called "Finding and previewing audio loops."  When I get to the step about clicking the Content Location drop-down list and selecting "Audio Library," I get an error message that says
 
"the selected content location preset referenced a missing folder:  'C:\Cakewalk Content\Audio Library'
 
Can anyone tell me the default location for this folder?  I tried searching all of my files on my computer and wasn't able to find it.
 
Thanks!
