You created the PCB without schematic, so you can igore the DRC error. The DRC just can help you to verify the design with schematic netlist.

Juanpa, The DRC errors you see are because, in two places, you have tracks with different net names going to the same pin. If you had created your PCB from a Schematic this would indicate a problem but as Support says, because you have created the PCB without a schematic, you can ignore the DRC errors.
