MS3x CAN error
 

I've been having a hell of a time getting my car running and idling properly, but that's a whole different story.
I was adjusting my req_fuel value right after changing my spark plugs and now I keep getting this error

The CAN numbers match in my project properties and my CAN settings and in communications, the MS shows up and connects.
what is going on??????
