1) Back up Hard drive crashed.
2) Managed to get most all the CWB off the HD during the last session it came alive for me.
3) I specifically left old projects to the last that I knew I had backed up on CD ROM and DVD.
4) Then Hard drive totally died, it was no longer showing up as a drive, and these old projects were not recovered.
5) Got all but one of the CWB (bundles) that I saved years ago (Sonar 2 or 3 probably) off the CD and DVD onto my new backup.
6) This one very large project on CD ROM would not extract no matter what I tried and kept crashing WIN 10 explorer.
7) I thought...why not try to have SPLAT open the CWB direct from the CD ROM ???
8) Success...Sonar opened the CWB and I was able to save on my new hard drive.
Amazing !
