Not receiving confirmation email after install

I have been trying to install wordpress onto my godaddy website for over a day now and am having some real issues…

First I started by purchasing a wordpress account ($99 bundle) and thought I needed to map my domain name to the blog…Shortly afterwards I realized I needed to install wordpress on my FTP server if I wanted to use a custom theme, which I do.

After deleting the mapping and refunding the purchased account I went to godaddy.com installed wordpress, gave all the proper information it asked for and am not getting any kind of confirmation email from wordpress…

each time I try to access my website at https://www.kwepunha.com I get this error message “Warning! Domain mapping upgrade for this domain not found. Please log in and go to the Domains Upgrades page of your blog to use this domain”

I am not sure what the problem is but I just noticed that the website will work on my pc computer but it shows the error on my mac…any help would be greatly appreciated!
