I got it working after physically unplugging the USB cable from the computer.  It takes a couple of tries but it works now.

Thanks!

I have two tinyscreen+ and for one of my devices, I keep getting the following error message when trying to upload a sketch.  I'm running Windows 7 and Arduino 1.8.1.  Has anyone else seen this error?
