If no one replies to your topic, it's probably because no one has any suggestions for you to try, or your topic has moved too far back in the listings, and anyone that might be able help, hasn't seen it.
In the case of no one having any suggestions, I would try Google.
If it's moved too far back in the listings, you could try "bumping" the topic.
Go to your topic, and add additional information, if you have any, or simply type bump
, then add reply.
This will "bump" your topic to the top of the forum list, where someone who hasn't seen it before, may see it this time.
Just don't over use it.
Once a day, for a couple of days, would be sufficient.
If you still don't get a reply, then it's because no one has any ideas, and it's back to Google.
No one, in these forums, is going to knowingly ignore your topic, if they can help.
Re-posting your topic will only get you a PM from a Mod, notifying you that double posting is not allowed, and the new topic will be deleted.
