Question : https error for my website

I just purchased an SSL certificate for my website, but it doesn't work. I've done this before numerous times for other websites and it's worked fine.  When I go to my website, I get the following error message:

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Default.aspx

The website address is:

https://gospelharvest.org

Can someone help me figure out what I'm doing wrong?

I'm running windows sever 2003, with IIS6.

Answer : https error for my website

Your site has
www.amazingfacts.org , amazingfacts.org  

and not gospelharvest.org
in the certificate
