On the Captcha window, you will see "refresh" icon (two arrows going in circles). If you click that icon, it will give you a new set of words. There is also an "audio" icon, which will speak the words to you (please turn on your speakers). If you continue to have problems, more than likely, your browser settings need to conform to the technical specification outlined on the registration page. You'll need to turn off all pop-up blockers, and set your browser to accept cookies. If you continue to have problems, please email customer support for assistance.
