Problems reinstalling wordpress

I isntalled worpress first time at christianalive.com without any problems but made a mistake that i didnt put it in https://www.root folder so that means i couldnt see the the on the dormain christianalive.com.I would only see the blog if i did christianalive.com/wordpress. I tried sorting that out but i couldnt so i delete the wordpress folder completely.

Now i am trying to reinstall it but its coming up wierdly and it still seems to go to the original christianalive.com/wordpress even though i have deleted all the files associated with this. i have tried twice without success. What do i need to do please. i have very basic knowledge of html.
