I'm not sure which program is producing this error but there appears to be more components in the net list than on the schematic. Can you show a scjhematic with the node numbers added to it?
Yes, the netlist doesn't belong to the schematic circuit. Please come back with consistent data. Even if you don't fully understand SPICE netlists, you should see that the component designators must match the schematic.
The schematic however looks like Vx is placed off-grid, without connecting to wires, which most likely causes the error in this simulation schematic.
