I would take the remaining "unused" pin, bend it over so the tip is touching or almost touching the "positive pin." Then add flux and a dab of solder to fill in the gap. If it works, you now have an electrically and mechanically sound pin to solder the driver lead to. This extra pin will be either for nothing, or for a photodiode, so who cares if that gets blown up.
That just might work!
