Apache wont start after attempting to install SSL

Below is what my VirtualHosts look like in httpd.conf

<VirtualHost *:80>
  # Admin email, Server Name (domain name) and any aliases
  ServerAdmin [email protected]
  ServerName  mydomain.com
  ServerAlias www.mydomain.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.php
  DocumentRoot /home/mydomain/public_html/mydomain.com/public

  # Custom log file locations
  LogLevel warn
  ErrorLog  /home/mydomain/public_html/mydomain.com/log/error.log
  CustomLog /home/mydomain/public_html/mydomain.com/log/access.log combined
</VirtualHost>

<VirtualHost *:443>
  SSLEngine on
  SSLCertificateFile /etc/httpd/conf/ssl.crt/mydomain.com.crt
  SSLCertificateKeyFile /etc/httpd/conf/ssl.key/mydomain.com.key

  ServerName  mydomain.com
  DirectoryIndex index.php
  DocumentRoot /home/mydomain/public_html/mydomain.com/public

</VirtualHost>

I'm using the latest version of Apache on CentOS and there isn't any error being generated. Apache just will not start. Any ideas what I'm doing wrong?

UPDATE - Found these messages in the error log:

It can not find /etc/httpd/conf/ssl.key/mydomain.com.key file.

In the logs you have:

[Tue Mar 16 02:07:57 2010] [error] Init: Private key not found

The related configuration is:

SSLCertificateKeyFile /etc/httpd/conf/ssl.key/mydomain.com.key

You need to install the mod_ssl package
