Thanks. I am using the FTDI port and wiggled some plugs, etc and now is loading ok. I assume when I was getting that error the mayfly was plugged in and turned on because when I attempt to load with the pwr switch turned off I get the following error:
avrdude: ser_open(): can’t open device “\\.\COM4”: Access is denied.
avrdude done. Thank you.

I guess a bad connection somewhere.
