No, you shouldn't post a new question, and—as you experienced—doing so will result in the question being quickly closed.
Stack Exchange is meant to create lasting bits of information: canonical pairs of questions and answers. Recreating the same question over and over actively harms this project.
If a question hasn't received an appropriate answer yet, there are several things you can do:
- Update the question to clarify the problem or update with what you've found so far, making it easier for others to contribute
- If there are answers already, revise the question to explain why the problem isn't solved by the existing answers
- Offer a bounty
All of these things will bump the question to the top of the active questions list, just as creating a new question would.
And just to clarify how bounties function; you mentioned in the comments that you haven't offered (or won't offer) a bounty because:
Right now there are so many bounty questions (diablo 3) that you'd actually have to look for the question in order to actually see it. If it was a new question, it might attract new questions, and as always, new edits or answers "bump" the topic back to the top.
Firstly, as mentioned above, offering a bounty bumps a question just as an edit or new answer would.
Secondly, the featured tab is ordered by how long the bounty has before it expires: your bounty will eventually appear at the top of that list.
Finally, this isn't 'nam: there are rules. Your question isn't more or less special than the other questions that haven't received much love. The bounty system is intended to be a fair way for people to "bump" their questions in an orderly fashion by paying reputation to entice people to answer. Trying to jump to the head of the pack, so to speak, by re-asking your question and without backing the bump with reputation is kind of a cheese move. Imagine if everyone did that!
