Can't get into site

Hi,

I am very NEW at having a website and messing around with any kind of code.

I use the Magazine Basic theme. My website is at natchristian.com

I hardly ever go there, but I decide to finally start tinkering with – customizing the front page, even though I had already installed Magazine Basic.

All was going well. But then I wen into the “settings” page. I went to the section where it said something about the adding a domain address that is different from WORDPRESS. So I tried to put in another name in that spot, then I got a “ERROR – page not found” page. I went back and re-typed in “natchristian.com”, but now I still get a “ERROR page not found.”

So now I can’t get into my website.

If I go to natchristian.com – I am able to get to my home page, but all of the formatting is off and when I try to “Log In”, I get a “ERROR – page not found” page. So I acn not get into my website.

I wrote to the person who created MAGAZINE BASIC and he said:

“You have probably messed up the domain redirection in WordPress. The only way to fix it is to log in to your server and change the database under the options table so you can reset your URL”

I have no idea how to do this.
I talked to my SERVER (NETFIRMS) and they were not sure if this would work and they didn’t not know exactly what to do – or where to find the info that is suggested to change.

Is there an easy way through WORDPRESS? Remember, I can;t get INTO my website, because when I hit “Log in”, I am directed to and “ERROR page not found” page.
