Just wanted to add few information.

IF you install a plug'n play module , you won't see the configuration you just did.

When Atomic detect a plug'n play module it switch to plug'n play mode and ignore the normal start up config.

But you can add your own config in the list of plug'n play module.

To do that , just run : PLugnPlaymanager.exe and click on "Add existing config" button.
