MyBB Community Forums - HELP! ACP is messed up and forum is messed up!

I tried to change the web URL of my forum, but it's not working and now the ACP is messed up!
It was forums.concept-gaming.net, I tried to change it to concept-gaming.net/community though, but it messed up and is still on forums.! The ACP allows me to go to the first page, and that's all. It makes me login again, but it won't allow me to pass, just brings me to ACP login screen again.
I also do not know FTP info.
HELP!

Through the ACP, all I did was change the web URL and cookie domain/path.
Now it won't let me change it back due to not allowing use of the ACP.

You can't just change the URL. You need to move the actual files to a new directory. If you don't have FTP access, you'll need to contact someone who does.
