ColdFusion Won't Accept Network Solutions SSL Cert

I followed these instructions and it said "Certificate was added to keystore":

Manually import a certificate

1. Go to a page on the SSL server in question.
2. Double-click the lock icon.
3. Click the Details tab.
4. Click Copy To File.
5. Select the base64 option and save the file.
6. Copy the CER file into C:\ColdFusion8\runtime\jre\lib\security (or whichever JRE ColdFusion is using).
7. Run the following command in the same directory (keytool.exe is located in C:\CFusionMX7\runtime\jre\bin):
   keytool -import -keystore cacerts -alias giveUniqueName -file filename.cert

from this url:

http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Tags_g-h_09.html

Except the location was d:\jrun4\jre\lib\security.

And this works: <cfhttp method="get" url="

but this does not: <cfhttp method="get" url="https://www.missionlinen.com" />

Why and how do I get the cert to work?
