Authentication error message on my website

This was working 3 days ago, now it gives me error. I registered today, that didn't help. What am I doing wrong. It's on my website located here.

You need to register your site for the test to work. The speed test registration is a way for me to verify you have given credit for using the test.

Registration is painless and can be found here:

3 days ago, I had the system wide open so that anyone could download and run my free speed tests - I just trusted that everyone would register and give me credit (at least most everyone).

After reviewing the number of sites that were not giving me credit for my work, I decided to reactivate the registration requirement.

If you registered, you would have not problem running the tests. If you didn't, then the test would not authenticate until you do.

So, just visit the link above, fill in your information, let me know when you're done and I'll activate it.

Best regards,

Jim.
