Domain Mapping Plugin Problem

mywebsite.com I set the domain's A record to the IP address. 123.123.123.132 (just example)
I set the options IP address to 123.132.123.123

I go to mywebsite.com and it redirects me to myblogsite.com/wp-signup.php?new=mywebsite.com and not the blog that is setup for it.

when I go to mywebsite.myblogsite.com it redirects my to the signup page also.

when I disable the domain mapping plugin the mywebsite.myblogsite.com works showing the blog.

What do I need to do?

I've edited the wp-config file

I tried commenting out
//define('DOMAIN_CURRENT_SITE', 'mywebsite.com' );
//define('PATH_CURRENT_SITE', '/' );
//define('SITE_ID_CURRENT_SITE', 1);
//define('BLOGID_CURRENT_SITE', '1' );
like I read in some other posts.

I do not have an option for cookies in the config file.

Thanks for any help
