Lost wordpress directory

Hi, through my stupidity, I’ve fallen into a great problem.

I had installed wordpress on a website in the directory: dailesnams.lv/wordpress/
and was working on the wordpress version there to eventually replace the main site (sort of behind the scenes maintenance, so that the original page still works while i work on the wordpress version).
Just minutes ago I thought checking out in the wordpress install in general settings what happens when i change the “WordPress Address (URL)” and the “Site Address (URL)”, which were both set on dailesnams.lv/wordpress/, because that’s where wordpress is installed for me. I changed it to just dailesnams.lv and horror of horrors, I’ve lost my directory! i cant access the admin panel through anything, not: dailesnams.lv/wp-admin/ or anything!
How could I get it back to the old /wordpress directory??
