If you do not have access to the latest CSA CD, you can download it by clicking here. I know that acs reset-config will solve the issue, but i have a problem here, the license file will be deleted as well.
If none of the steps above work, it is required to rename the X:\WinCSI\CSA directory to X:\WinCSI\CSAOLD (where X represents the drive where the program is installed), reinstall the latest CSA installation CD, download CS Connect updates, and re-apply the CS Connect updates. Use a right-click on the CSA icon and choose Run as administrator to open the application.Content Awareness override mapping file
For additional information on running as Administrator, refer to Permissions guidelines for the CS Professional Suite.
Copy past the DRM update URL and check if it helps. This error message can occur if the Creative Solutions Accounting (CSA) program is opened while CS Connect updates are being applied. The component intercepts the Microsoft XPS Document Writer and enables ABCpdf to import an extended range of file types via XPS. Then the user deletes the license and reopens the encrypted file and obtains the license.
