This might be a permissions issue. Check the permissions on that file. Do you have write access?~Lilly

How do I check permissions on a file? How can I see if I have write access?

  1. Open the Finder window2. Navigate to the location3. Highlight the file or folder with a single click4. Control-Click on the file and select “Get Info” from the pop-up menu5. At the bottom of the info window is "Sharing & Permissions:"6. Click on the triangle to expand it7. Your permissions are then displayedYou should have read and write on the file and on the folder that it is in.For a nice overview of permissions, look at http://support.apple.com/kb/HT2963
