Unknown module error

Hi guys,yesterday i tried to launch my backup copy of Demon's souls,i can see the icon in the menu but when i try to launch it i get this message error: LDR:Unknown module 'cellM2BCdec'.Is it because the game is not supported yet or i miss something? Thanks

Didn't he say backup copy .-.

Yes. That's just a generic message. He didn't mention piracy so no warnings were issued.
