I have to reinstall CS5.1 and am getting error 213:19

I have solved this by perusing the forums and following the instructions in this guide:

Error 213:19 | Problem has occurred with the licensing of this product

"Make sure that your user account has full permissions (Read and Write) on the SLStore folder."

Fixed my issue!!

This has forced me to reinstall all of my programs including Photoshop CS5.1, unfortunately I keep getting the following Configuration Error: "A problem has occured with the licensing of this product. Restart your computer and re-launch the product. If this problem still occurs after restarting, contact Customer Support for further assistance, and mention the error code shown at the bottom of this screen. Error: 213:19" I have restarted several times now, and get the same error every time I try to run Photoshop. What does this mean and how do I fix it? Thank you!
