Hi, customer has KUKA KR30 robot with KRC4 cabinet and KSS version 8.3.
As far as I know, no modifications have been done but suddenly the subprogram folders seem to be empty in operator mode. If they switch to Expert mode then they can see the subprograms in folders but they can`t select those to run the programs and all of the icons of dat. and src. programs look like they are text files now. Opening the programs for modification is available.
They have tried to reboot the system but that wasn`t the answer. My colleague was suggesting that some changes have been done in Windows but I don´t know about that. Has anyone encountered same kind of behavior before?
The menus in photos attached are in Finnish but maybe you can get some hints about the situation.
