Just to make sure you are following the correct guides, can you confirm you are using these guides
If you are having problems uploading sketches the problem might be that the Edison memory is full, try doing the flashing guide or if you have access to the linux console, do the command df –h and see how much space you have left.
Yes, those links are exactly what I used. I have been through them (very carefully) a total of 3 times now. Since I have no done anything with the Edison, except try to upload the Blink Arduino example, there should not be any space used up. df -h shows lots of free space available. /home lists 2.2 GB available.
