too many redirects bug from geodir_buddpress

This plugin has been working fine for me, but suddenly today it can’t be enabled without bringing my site down.

I get this error:
“Can’t open page. too many redirects occurred trying to open ‘mysite.com’/wp-admin/admin.php?page=geodirectory&tab=geodir_buddypress&subtab=gdbuddypress_settings”

I have to go in via ftp to kill the plugin to get control back. This error happens as soon as I try to enable the geodir_buddypress plugin. All the other Geodirectory plugins activate OK. I tried deleting and reinstalling this plugin but no change.

Thoughts?
