Big Problem, need help!

Hi all. (i posted this in another forum, and realized this was a more appropriate location)

I was developing an update to my website at

brawlplus.net with wordpress at brawlplus.net/wordpress/

Since the website was mostly done, I thought I could copy the contents over to the root, and then edit the admin controls to say that wordpress was stored at brawlplus.net instead of brawlplus.net/wordpress/ in the general settings menu. After I editted that information, I quickly realized I made a HUGE mistake and I have zero ideas how to fix it. I can’t log in to my admin controls to fix it, and am not sure where to go or what to do.

Please help!
