It happened to me just yesterday. Just terrible.

No, not at all. A bounty is only meant to feature the question and give people incentive to try and help you.
Assuming this is the question you mean: http://stackoverflow.com/questions/2534595 then as far as I can tell it worked - you got an additional 3 answers you probably wouldn't have otherwise gotten without the bounty.
It may be that none of them solved your problem, but there's no guarantee that your question will be solved - just that it will be featured.
