Cannot upload to board ... HELP PLEASE!!

The error indicates you're doing an "Upload Using Programmer", rather than a standard "Upload". Upload Using Programmer is done via Sketch > Upload Using Programmer, holding the Shift key while pressing the Upload button, or Ctrl + Shift + U. Upload is done via Sketch > Upload, pressing the Upload button without the Shift key held, or Ctrl + U. You want to do a standard Upload, not an Upload Using Programmer.
