I have a desktop mic for recording.  I recorded about 11 slides of audio and the mic calibrated and recorded perfectly.  I shut down my computer overnight.  Saved all my files and closed the captivate project.  One restart of my system and captivate 2019 the mic no longer calibrates or records in captivate.  I unplugged the usb mic and recalibrated it on my computer sounds, recording device.  Captivate was still not picking up the mic.
