Can no longer log in to the admin

[airbrushtour]

I'm not sure why, but now I can no longer log in to my admin. I have saved all my login information and I know that I'm logging in correctly. I've even had the system send me a new password, which doesn't work either.

Anybody have ideas?

I also have a wordpress blog installed on this domain and I'm getting 404 errors intermittently when I try to access the admin page. Could there be a conflict with my blog maybe?

I looked on my domain's .htaccess because sometimes Wordpress rewrites its own .htaccess file. Is there something in that file that needs to be there for ZenCart to work maybe? I'm desperate. Any ideas would be welcome.
