Try tracing tpl.hitechcreations.com with pingplotter. That should point out where the problem is.
Now, it sounds like pingplotter isn't working for you. Can you describe exactly what you mean by that? What happens after you press the TRACE button? Wait a while if you don't get anything right away, and let us know what you eventually get. It should show you SOMETHING, even if it's that it can't resolve the name, but it may take a few minutes to show an error.
