To get the full functionality and flexibility of our templates you will need to make modifications to the Photoshop files (PSD). To properly modify these you will need either Photoshop CS3 or higher or Photoshop Elements 10 or higher.
If you do not have either we recommend that you pick up a copy of Photoshop Elements 13. You can find it usually for less than $80, and sometimes for $60-$65. Use the following link to find it on Amazon http://amzn.to/1NpPtmV.
