Please stop replying to your own post a few hours after posting your question. It won't help you to get a reply faster.
People here are helping on their free time, without being paid, you can't expect the service of a company that guarantees 24x7 support.
If people haven't replied so far it is perhaps that:
- they don't know the answer
- they know the answer but didn't have time to answer it yet.
- they didn't had a chance to read your post
