Im new to this software but I can not seem to get this circuit to run properly! It just keeps saying cannot find solution when its meant to trigger the next light.

I'm pretty sure that most of the right side of this circuit is wired incorrectly. But I'm no 555 "guru" lol. I would double check the schematic if I were you, paying special attention to where the output of each chip should go, and looking closely to the anode/cathode connections of the LEDs..
