Thanks for your reply, yet the preference menu is exactly which I cant seem to relocate correctly.
For some additional info: the error message I get is: 'Find Missing Audio'.
I copied my old project files to the default directory: C:\Cakewalk Projcts and Sonar does find the (old) projects.
What seems to go wrong is the path to the Wave Files:
The standard path is C:\Cakewalk Content\Audio Library and I used to have all my samples here since this is also where the native sound files reside and I wanted them to be in the same directory but now I have put my samples on the new HDD (B:\) and made shortcuts from the standard path to the new B:\ HDD.
I also kept the structure of the subfolders intact so it seems to me only the root (C:\ or B:\) is the culprit.
When I let Sonar scan for the missing audio it only scans my C:\ drive and not the B:\ and I see no option to add this drive to the search..
I also tried changing the path of the Audio Library to the new B:\ HDD but even then Sonar doesn't find the files.
PS: Ofcourse I reinstalled the 3rd party synths and this all works fine.
