My site is coming up as a Wordpress blog - how do I make it a Wordpress website - URG

I am trying to download the Exposure Theme in a zip format, but it is not coming up.

If my site is coming up as a blog do I have to delete it and start again as a Wordpress site. If so how do I delete it and start again.

I guess you may convert your account from AlterSite to AlterBlog, you can do it in your AlterVista control panel
