Can't login on musescore.com but able to on musescore.org

Hi, I have a working account here on musescore.org, but when I try to log in on musescore.com I get a "page not found" result. I have Facebook connected and logging in with Facebook has the same result. When I try to register with Facebook I get "page not found" as well. When I try to register on musescore.com with my email it says that email is taken.
Is there a way around this?
thank you
