Locked out of admin after deleting subdomain

Hello,
I really need help and can’t find my problem on the forums. I got locked out of my admin account by trying to move my WP from a subdirectory to a domain. BUT! My admin was also in the sub-directory. I thought that I would still be able to log in by typing in the link but keep getting a 404 error mesage refusing permission.
This is what happened?:
My old log-in was in
mysite.com/wp/wp-admin (instead of mysite.com/wp-admin)

I found a tutorial on how to move files and a step was

1 – Go to Settings > General and remove the subdirectory from the URL for both the WordPress Address and Site Address. Be sure to remove the trailing / . Both addresses should simply end with .com or .org or whatever the domain type is. Click Save Changes.

Well the moment I did that I lost access to everything. I need to put that /wp/ subdirectory back in so I can fix things but have no way to do it.
I have access to the server end but am not tech savvy enough to fix it from there.
I do have all log in info, just need access.
The site is comics-scholars.com
Can anyone help?
