In your schematic, you need to rename your LM317 from U1 to X1 . Spice expects that all subckt components' reference designators will start with 'X'. I think there is a gschem attribute which will rename the part from U... to X... during spice netlist generation, but I don't remember what attribute that is. The easiest thing is to just change the name in the schematic.
