You broke one spoke, had it replaced and another broke right near it? The spokes are pretty much done by this point.
Look at it this way, breaking one spoke on a wheel is a start of a domino effect, the rest will follow in short order. You popped another spoke. If you ride around on that wheel with a broken spoke, you *will* break additional spokes.
At this point, I would rebuild the wheel with new spokes and have the wheel properly tensioned. The spokes break generally because the wheel doesn't have enough tension. Too little tension causes the spokes to break by the heads (where it enters the hub).
