Did CNAME Record and Google Apps break my site?

I created a new email address on my server and wanted to take advantage of Google’s excellent spam filter by integrating my new email with Google Apps. Also, because I wanted to be able to go to: mail.workingauthor.com to get to my webmail I created a support ticket with my host to point “mail” to “ghs.google.com” as per Google’s instructions. I waited for the DNS to propagate overnight and this morning I find that none of my links work. Apparently, the server searches my directory file structure rather than staying within WordPress.

Forgive me if I’m not using the right words to describe this; I’m new to web development.

Basically, I don’t actually have a directory called workingauthor/film but my server tries to send you there now.

Is this the result of the CNAME record? I’ve deleted my account with Google Apps, deleted MX records and created another support ticket to undo the CNAME record. I’m still waiting for the DNS change to propagate, but I just wanted to get other’s thoughts in case this didn’t resolve the issue. What else can I do?
