Try cutting the copper track and isolate the rest of the circuit from the output of the voltage reg and then measure the input and output of the reg, you should be able to find out what is dragging your voltage down,if its ok solder it and cut the next part of the pcb and so on ,if its a problem with your pcb, then its better to find the fault on this pcb first, as the same fault could be on your new pcb to, give it a try.

I recently had a faulty -5 v reg, it did weird things when under a load.
