404 Error

I am using the domain mapping plugin and I am not sure what I am doing wrong.

I have this red box at the top reading:

You use old version of /home/sphynxma/public_html/ariseibohrm.com/wp-content/sunrise.php file. Please, replace that file with new version which is located by following path: /home/sphynxma/public_html/ariseibohrm.com/wp-content/plugins/domain-mapping/sunrise.php.

I am copying the exact file and I can't get past this.

Please help.
