I deleted by mistake all teach pendant directories and now when I start the controller it says: “RobotWare Boot Application 3HAC7927 - 6.17, No system is currently loaded in the controller, Please initiate boot sequence!” How do I reinstall the system? Is this a huge problem or I can get everything back on fairly easy? (I do not need old programs and data, just for the robot to work). Thanks, Alex ---

Do you have any backups? You can recreate your system from a backup in system builder or installation manager, depending on which rw version you had. ---
