WordPress MU

I have enabled registration but I am getting some kind of loop when clicking the link to /wp-signup.php I get an error with Firefox: "Firefox has detected that the server is redirecting the request for this address in a way that will never complete." I checked the .htaccess file to see if there was anything in there that could be causing it but nothing turns up. I also have a bbpress integration and when a user registers for a new account there, it works no problem.

I had originally installed my wordpressmu under /wordpress-mu/ but then moved it to the root later. My config file says:

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');
define('VHOST', 'yes');
$base = '/wordpress-mu/';
define('DOMAIN_CURRENT_SITE', 'cjmoloneys.com' );
define('PATH_CURRENT_SITE', '/' );
define('SITE_ID_CURRENT_SITE', 1);
define('BLOGID_CURRENT_SITE', '1' );

Is wrong with editing by hand and chaning the $base = '/wordpress-mu/'; ?? Everything on my site works fine except registrations. I don't even know if this is the cause.

Yeah, you'll have to edit the file and change that to "/"

I changed it to "/" but still the signup doesn't direct to anywhere at all. Anyone have thoughts as to what could be causing this error?
"Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

I went into the database and updated the wp_site table with the correct URL. Now when I click on "Create Account" it no longer gives the error. It directs to a page with this URL:
http://cjmoloneys.com/wp-login.php?redirect_to=http://cjmoloneys.com/register

however... you cannot register there. You can only login. I do have registrations enabled for users but not blogs. Any idea what could be causing this?

Do I need to re-install?? I'm not sure how I would go about re-installing because I have my bbpress installation already integrated as well as buddypress operating with a couple users. Anyone know how to retain this data and reinstall?
