In theory if you have power to both banks of the input power it won't matter that the track has been burnt out.
2 things of concern though.
-36V is right on the maximum 36V that the OKI78SR regulators can handle.
-there are a couple of possible reasons that the track fused. The 1 I'd be most concerned about is the jumpers to select the input voltage. If that happened to have been in the 5V setting you may have damaged all sorts of things which could present a short circuit and potentially fused the track.
