I dont know if this helps,
but are you sure you let the image finish building, if you are unsure you could allways try the button called rebuild image.
In /usr/share/pluto/diskless you can delete the XX folder which represents the id of you computer, inside the image resides, i deleted the complete folder called 48
then went oni the pluto admin home page and on the Orbiter page i selected Rebuild image.
Hope this helps,
