There was an old thread from 2007 that you asked me about in a private message. I don't answer via private message because nobody else can benefit from the reply. You can however copy and paste paragraphs from the old thread if you have specific questions. So far there have been no specific questions only a generalized plea for help. We can't help you if you cannot tell us what you need help with.
