Hi bjkellett,
It looks like you have not selected the right COM port or the driver has not been installed properly. From the message you provided, it shows that you are using COM 1. Usually all computer have COM 1 already being used.
When i do a firmware update this is part of the message:
COM PORT 5
Converted COM Port COM5 to tty port /dev/ttyS4
Notice the "COM PORT 5" that what i have selected in the IDE and confirmed from the Device Manager. Can you provide a screenshot of your Device Manager with the "Ports" list expanded. and a screenshot of the Tools -> "Serial Port" expanded?
Regards,
