Breakthrough.tga is on the output event. It is the file name that the sequence is saved to. The reason it gives the error is because that scene is currently set to render to a network path. Just remove the last event in the sequence, "breakthrough.tga", to remove the output event and stop getting the error. You may also want to replace the output event with a new one that renders to an avi on your computer so that you may view the completed effect.
