Hi Matt, I'm getting the same error from time. It ends up going away, and I can't aways remember what I've done to fix it. One time it went away after I opened preferences and pressed ok. (Similar to Jim's noise problem). The other time I changed the sampling rate in the Quality category of preferences to 48000, and it went away, I then changed it back to its normal value and it was still fine. I'm not sure whether or not it's connected to having another program sending audio to another playback device.
