avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Try using 1.8.9 instead..... It worked for me (after installing 1.8.10 I git all sorts of 'new' error messages and couldn't upload, but after returning to 1.8.9 everything worked fine).....
