I'd suggest that if the answers to the original question didn't solve your problem, you don't have the same problem. If and only if that's the case then it is perfectly acceptable to ask your own question.
To make sure it isn't a duplicate and doesn't get closed as one, you could:
- Hyperlink to the original question from your question, and explain why your problem is different and why the answers to the previous question didn't help.
- Take care to explain your problem well and include a (preferably, compilable) piece of code that illustrates your specifically problem.
But note that posting your own version of the question as an answer on the original question is never acceptable, regardless of whether you have enough reputation to post comments or not.
