I have a 1769-L33ER compact logix plc that is currently running v20.12. The program does not have any source protection set up. I can upload the program and do everything necessary with all routines. After saving and closing rs5k, when I open the program again, I cannot open any of the routines, they all say 'source not available'. I have to upload from the plc again in order to view/edit logic. Everything else is still accessible, tags, data types, I/o config, etc. Has anyone else ever run into this problem?
