Sorry to hear that mimoLive is not doing what you want. If you have a minute, I would really appreciate if you let me know what was missing.
To remove the Virtual Camera, remove these two files and restart your computer:
/Library/CoreMediaIO/Plug-Ins/DAL/mimoLive Virtual Camera.plugin
/Library/Audio/Plug-Ins/HAL/mimoLiveVirtualAudio.driver
