If your question is why nobody wants your models, well, there is a trust issue. There are scammers who try to trick people into using their stuff (using a fake identiy) and then accuse them of stealing and then ask for compensation. Trust can only be built up over time.
If your question is a technical one you really should add more information. What you were doing, the xml code you used, what files you changed, the error messages you get...
The more details you provide the better.
