Andres: Thanks so much. That did the trick. I was able to find my old Sonar presets (same Key name, but under "Sonar"). I exported that key, and exported my Cakewalk Bandlab key, just to save them. Then, I opened them both in a text editor. I copied the first line from the Bandlab key (which is its name/location in the registry), and I pasted it into the Sonar key (which had all my presets), then "SAVE AS" a new key file, so I didn't overwrite the original key. Then, I installed that new key over the original Bandlab one in the Registry and it works like a charm.
I had about 15 different "Export Audio" presets that I had made over the years, from the early times of Sonar, and I didn't want to have to recreate all of them. This saved hours of work! And I tried them in CW Bandlab and they work. Thanks again. Really appreciate it.
best, --john
