I am not surprised to hear that, I haven't bothered with LDD for years, they don't keep every piece forever. That's why best to find an alternative or convert it into that alternative.
Oh, I bet now they can't replicate over 90% of parts from Bionicle and Hero Factory, since its costly keeping those machines that create particular piece shape.
My friend told me some guy infected his harddrive with a virus and he lost all his work including his project on blood city. And ever since he vanished.
Damn how random coming across this. I see you still keep mocing spark alive. Its too bad Edictarts seized to exist.
