I was afraid you'd say something like that. Nothing in the console about that.
I have changed the folder structure and removed the Mvam from the Sneaker respectively Autoload to an own folder. Since my KM is unique now, no one can help me.

What bothers me a little that sneaker has rewritten the entire XO menu for his Mvam- and the CoreEject-Mods. A simple CreateButton would have done it.
The Core Eject Mod I have already modified so that it is loaded via QBautostart. I also moved the button to the engineer menu. This could be one of the reasons why it no longer works for me. I think I'll embed the Mvam mod just about QBautostart in the Bridge menu.
