GarageBand: Error while trying to synchronize Audio and MIDI.

This error recently started popping up for me while using garageband.

GarageBand: Error while trying to synchronize Audio and Midi
Sample rate xxxxxx recognized
Check conflict between garageband and external device

When I use garageband, my input and output are usually set to my scarlett 2i2 interface and I've never received the synchronizing error before today. I am not using any Midi.

I've checked the Audio Midi Setup tool to make sure that my format is at 44100.0Hz and have set the "sound" in system preferences to use my scarlett 2i2 interface for input and built-in system for output.

Can anyone help me out with why i'm receiving this error?
