?? I can’t upload image. The message says hr=c0040402, RobHelperFactoryImpl.cpp[576]

Which version os RS and RW do you have?

Have you installed latest version of RW?

I usually open system builder and make a copy of the controller (just in case). Then modify the existing system and go through the prompts…works sometimes to restore the system.
