[SOLVED] wp-admin login fails, changed default directory

Hi All,

I've made a mistake in the configuration in the atahualpa settings. There is an option in wordpress to change the default directory. i can't remember the name of the option, but i think it is the settings. i've change the default to directory to my with site with the page id "?page_id=2" behind it. So my default site is now www.meerdanschoonheid.nl/?page_id=2. what happens is that i can't access wp-admin anymore. So when i type www.meerdanschoonheid.nl/wp-admin i will get a redirect to http://www.meerdanschoonheid.nl/?pag...%2Fwp-admin%2F.

does anyone know get it back to default so i can wp-admin again? what should i resote from back-up?
