Hello Laszio,
Are you saying you don't have the schematic for this layout? If so you can try to change it to a netlist driven design. In the pcb/logic directory there is a file netlist.aug. You can change this to netlsit.kyn and then edit your project file so that the layout is driven by the netlist. If you don't have the library you can attach any library but will not be able to draw any data from it.
