Word Press Landing Page error raw install

I made a mistake and have messed up m y landing page. I did not read the directions. I know I was a bad boy! Still, I need some help./ I changed the GENERAL panel from the regular root directory (onedoorministries.org/wp/) to be just onedoorministries.org.

I followed the first few steps in the wordpress codex ... (3) In the box for WordPress address (URL): change the address to the new location of your main WordPress core files. Example: http://example.com/wordpress
(4) In the box for Site address (URL): change the address to the root directory's URL. Example: http://example.com
(5) Click Save Changes. (Do not worry about the error message and do not try to see your blog at this point! You will probably get a message about file not found.)

but unfortunately I did not read ahead to the next step ...

(6) Move your WordPress core files to the new location (WordPress address).

Now I cannot get to onedoorministries.org/wp/wp-admin.

I cannot get to onedoorministries.org/wp.

I cannot get to any of the /wp files.

I used the online file manager, and searched through several files using Code Editor and Command-F, but I could not find a file containing the expression "onedoorministries.org".

Can somebody help me? I am a bit flummoxed.

What do I do?
