I did a one click install of joomla, and am waiting for the email with instructions. It gave me a "10min" message, but it's been much longer than that, and neither my site's mail, nor the mail I registered with have had anything come in.
You might see advice of completion from within Panel.
Panel > Support > Support History
You can also try SFTP into the place you installed to see if the files have been installed or not.
They're there, the installation must have just finished. I'm sure I can work though this pretty quickly =P =P
