Sorry, I have no suggestion for your problem.
It is quite possible that everybody else that has now seen this thread (112 up to now) also didn't have a suggestion, so they just didn't reply.
The most probable scenario is that no matter how many times you bump the thread, it will not make people come with an idea about how to solve the problem.
But perhaps if you wait some more, someone that actually has a good suggestion to give and isn't around the temps right now because they happen to have a life will eventually come and have a reply for you.
PS: A side effect of bumping the thread is that it may get locked, because bumping is against the rules. It would be better to avoid this if you want this person to be able to reply to the thread.
