As I started my engine to export the csv file, I was greeted by the half-filled symbol on the dash and a service engine light.. After I uploaded the new firmware, everything checked out okay.

Terry doesn't think that the data connection was related to the error, but it sure was an odd coincidence. I'm just glad bms is based in California. I doubt he would have been as enthusiastic about helping me out if he was in the same time zone as me. I couldn't sleep without making sure my car was okay .
LOL if you unplug something in the ECU box when the ECU is awake you'll sometimes get a CEL.
