Program Download

Just recently started having problems downloading program to a Sparkfun Thing.

Tried a different Thing and also a different FTDI board.

As soon as it goes to download (or to open the Serial Monitor) I get an error on the USB/Com Port.

Tried every different USB port.

Any suggestions?
