Page Ok Screen – Can't Log In To My Site

Hello – I can’t login to my dashboard because my link letthemeatmusic.com/wp-admin is not working… I keep getting Page Ok , which is the same thing that you will see if you try to go to my website. I don’t know why I am not able to log in? All my content for my site is there. My website is not viewing properly either but first I need to get into the dashboard. Please advise as to how to do that if the wp-admin and wp-login links are not working.

Thanks,
S
