Suddenly I’m getting no audio input from my Digi 003

[centuryson]

Hey guys, really need some advice. I’m using a Digi 003 with an iMac and am on Pro Tools 12.4.
I recently upgraded my OS to the most recent High Sierra and ever since I can’t get any audio into Pro Tools. My Digi 003 is a recognized device on my Mac and I can see the computer is getting audio, but on Pro Tool I get nothing. My I/O looks right and Pro Tools sees my Digi as a device. It even plays audio out, but I can’t get anything to the inputs. I tried with other software and was successful with Guitar Rig and Reason.
Is this something that might be corrected my upgrading to ProTools 2018? Could there be something in the I/O I’m not seeing? I admit I am a little bit of a novice and would appreciate any advice.
Thank you to the community for your expertise.
