I'm glad that posting the command line windows (I thanked my friend) brought you to this very simpel remedy of only removing the MDM config file. I have to process some mixed feelings
of spending many frustrating hours behind the PC's thinking that my three different Windows/Java/MDM installations/machines caused the problems, while they did not. But that's life, I know. At least now you can probably solve this bug in MDM and that's what this project is also about. Thanks again for your support and I think you can close this thread.
