点击“Continue with Payment”之后，总是显示下面这段话：
Whoops! You must use the navigation tools provided to move around within the Apply Online system; you may not type page URL's manually.
The page you attempted to visit was: http://apply.embark.com/lib/event/Payment_Event.asp?
Please press the "back" button on your browser to return to the previous page or login to your application again.

请大家帮忙解决一下。谢谢！
