I am using PLC Designer (Lenze) v 3.19.0.12851. I have been testing a program all week. Yesterday after going online with the simulator, Many of the debug buttons became grayed-out. Step Over, Step Into, Step Out, Run to Cursor, Set Next Statement, and Show Next Statement are no longer active. I uninstalled and reinstalled, but that has no effect. Any suggestions to get these buttons working again?
