How do I get rid of popping noise and error messages regarding the AudioBox USB 96?

After recording off an on one day I started receiving error prompts about the audio box not initializing and not starting correctly. It has stopped me, mid recording, twice. When it does allow recordins the vocal recordings come out extremely quiet. Also there is a popping noise coming thru the headphones. I then tried to use my blue yeti usb mic in studio one, however it isn't allowing me to record. How do we fix these problems? I have AudioBox USB 96
