Can't Listen to Track - Bias FX

Good mornin/noon/night, everyone

I’m recording some guitar tracks from DI, and using Bias FX to give it á proper tone. It was all alright while I was setting it up and testing, but when I added a track with EZDrummer, I stopped being able to listen to the bias fx track at all. Is there any setting up of input/output I’m doing wrong or something?
