Some Cakewalk processes may interfere with the reporting of audio file selection to VocAlign, and may result in the following error:
When receiving this error, please perform the following actions:
1) Right-click the problematic audio clip's header
2) Choose "Bounce to Clip(s)"
 - This creates a new audio file, with uncorrupted ARA metadata.
 - Please note that this process will bake in any Region FX that were present in the old clip.
3) Add your VocAlign Region FX again, and capture.
