ROFL. That's a self-signed certificate. It's not a legitimate SSL certificate. Whatever you've gotten needs to be removed and a real certificate put in place. Until then you'll just keep getting errors when trying to look at your site in SSL mode.
Further, if your hosting company has pointed your SSL traffic into an "https" folder, then they're forcing you into having to duplicate your entire site everytime you do an update. That's a very poor server configuration (very old-school, actually). If they have any clue what they're doing they'll point the SSL traffic to your main httpd/htdocs folder so Zen Cart can handle when to go into SSL mode or not. If they can't do that for you, find a host who can.
