Site Redirect Question

Hello, I'm a newbie, and I'm having an issue here..
once I try to redirect my web from example.com to example.com/new
I think i made a mistake, so i write example.com/new
Then I delete it from my redirect list, and make a new one.
Everytime i write down www.example.com, it does just fine and redirect it to example.com/new
but everytime I write down example.com it just come strait to example.com/new, eventho it's not on the list anymore.
What should I do? and i can't fine the .htaccess, eventho i also don't know what to do if i find it.
It's really frustrating.
