Yes, I have tried that 50 times+, but the BasicHome screen is still thereOk, in this case you have to change it with the Skin Editor.
open MPD++ Config, choose the Skin Settings Tab and click on the pencil right from the Skin Dropdown Menu.
Click on BasicHome (directly the first Screen in the List) and disable "IsDefault"
Click on ClassicHome and enable "IsDefault"
Save the Skin - finished...
