NOTE: If you used a version of the ide where the digistump add-ons were installed separately you must delete the digistump folder at My Documents/Arduino/hardware (windows) or Documents/Arduino/hardware (OS X) or /home/[username]/Sketchbook (Linux) or this new IDE install will not work properly and you will get library errors!
