WordPress site gone?

Hello there,

Today I thought I was smart by changing the URL of my WordPress site in the Settings menu. In the General tab I changed both URL’s from http://littlefishmusic.net/littlefishwordpress to just http://littlefishmusic.net. BIG MISTAKE! The site looked really funny, didn’t have any lay-out, so I started googling for a solution. I managed to access the database through phpMyAdmin and renamed both URL’s to what they were. Now I can’t access anything anymore, the browser gives an error “Error creating database connection”.

Did I do something wrong there? Any other way to fix this?

Thanks!
Marty
