You have enabled the 'no extensions' mode without making the accompanying change in IIS.   Unless you change your IIS configuration to run in extensionless mode (the details are in the instructions) you will continue to get 404 errors from IIS.

To get your site running again, you need to restore the web.config file you backed up before installing.  If you didn't back up your web.config file, then you need to FTP it down to your local computer, then change the setting in the 'dnnFriendlyUrl' section which controls the use of the '.aspx' extension.  You need to have a setting called pageExtensionUsage="AlwaysUse"

Let me know how you get on

Now that you have the site running again, I'd advise checking the extensionless-configuration in IIS before applying the changes to have the 'No extension' setting turned on.

You can configure your site for no-extensions in IIS, configure Url Master but with 'Always Use' as the extension handling option , then just request one of your pages without an extension ; for example - http://scienceofbusiness.com/consulting_services/  With Url Master handling the Urls, requesting this Url should work.  It will probably 301 redirect to /consulting_services.aspx, but if you don't get the IIS thrown 404, then you know you've got the configuration correctly set up.

Once you've got the site responding to extension-less Urls, then you can configure the 'Never' option of the Extensions setting.
