Giving WordPress It's Own Directory

I’ve had my website up and running at http://www.NaturopathToronto.ca for years, but it was time to update to mobile friendly. I installed wordpress at http://www.naturopathtoronto.ca/dir and built the new site, while leaving the old Expression Web site up and running. Now that the new site is ready, I want http://www.NaturopathToronto.ca to point to the wordpress site. I found directions on how to do that on YouTube here: https://www.youtube.com/watch?v=Jn9aWPG_QcY. It worked, yay! However, I was concerned that having the old site files still up might be a problem for Google (considered duplicate content). So I went into Expression Web and deleted the old site files from the remote website. On doing so the whole site went down, including the new WordPress site. Since then, I haven’t been able to get http://www.NaturopathToronto.ca to point to the WordPress site and I had to reupload all the old files in order to have a site up. I found directions on how to Give WordPress it’s own directory here: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory. But I can’t seem to get this to work. I can’t find a .htaccess file anywhere and my cpanel doesn’t have an option to display hidden files.

The WordPress site was displaying nicely until I took down the files from the old site. I have no idea why this would impact the WordPress site but that’s the only change I made that caused it to stop working.

I hope this makes sense!
