Snapshot Pro error - WPCONFIG Already exists

Hi guys, I've just restored a snapshot from my clubaereopanguipulli.cl website and I'm receiving the "wp-config file already exists" when I try to enter to my homepage... I tried everything I know of, but I can't seem to find any solutions to this...

Can you guys help me please? The only thing I did was to restore an snapshot I made yesterday, and it all went well, until I tried to go to my homepage, the admin area works fine and I can make any changes I want to my plugins, post's and pages, but cant enter my homepage.
