I recently upgrade to a new Mac computer so I could run Catalina and continue upgrading my Wirecast.  Everything had been working fine on the older version that was running on El Capitan but I've been paying for the upgrades to Wirecast and not able to use them for over a year now.  I'm now running Wirecast 14.0.4 on a Mac Pro 3.5 Ghz 6 core Intel Xeon E5.

My problem is that when I try to add my USB Microsoft Lifecam webcam it shows it as a selection but no video comes up.  The same thing when I try to add my Behringer USB connected audio mixer.  I can select it but no audio comes over.  Both these devices work fine in Zoom and Skype and they both worked fine in my old Wirecast on El Capitan.  I've tried changing the settings of the resolution but it just pops up a window saying an error occurred with the camera or the audio mixer.  What can I do to get these devices working again?  The Microsoft webcam works on my Mac through an additional software called Webcam settings. I also just tried hooking up a Q2n Webcam and it will not show the video as well but is select-able.
