How does moving the resistor and the LED "one round lower" change anything? There is still a
direct connection from D11, D12, D13, and D14 downward to D15, D16, D17, D18, D19, D20, D21, D22, D23, D24, D25, ... , D46. You have essentially shorted your LED through the transformer and one of the rectifier diodes with no current limiting. Must be a pretty wimpy transformer not to have fried the LED by now.
Please draw up a schematic and post it here to allow us to compare it with your Vero-board layout, as
@davenn requested in his post #2. We can't help you if you don't respond to our requests.
