When I installed I selected "Trial Version". I get this Configuration Error notice: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.
You have a permission issue with your SLStore directory. I would recommend completing solution 2 of "Configuration error" CS5 - http://helpx.adobe.com/x-productkb/policy-pricing/configuration-error- cs5.html#main_SLStore.
