You need to uninstall IIS. Failing that you can just switch it off. You can uninstall via the control panel and add/remove programs. To switch it off look for the services section in the admin tab (again in control panel).
This may be why admin didn't come up. I would remove IIS and then start again.
You did RIGHT click on the 'E'. Don't panic, this *does* work. I have had no trouble at all.
