Help with address

Hi,

I have a website called https://www.reapmidwest.ie. When I was editing in WordPress, all the pages, when I previewed them came out with the address https://www.reapmidwest.ie/wordpress. To fix this I removed the /wordpress thinking all would be ok.

This obviously messed up the directory and now it says file not found when I try to log in.

Can anyone help me change this back or tell me what to do? I probably need someone from wordpress itself as I cannot log in or do anything. Any help is much appreciated. I am an educational technologist with little knowledge of hosting sites or coding, website design etc, I am finding WordPress very frustrating to use and this just made things more complicated again.

Thanks,
Ciaran
