account details

I was trying to get some sheet music, but when I tried to log on, I discovered not only do you still have my old (at least 3 years old) email address, but when I attempted to change it, your system kept rejecting my password.
I am "rhban". I was robban@clubtelco.com, but am now with robertbannister@iprimus.com.au.
My password, which I had recorded in Dropbox was always "balrog", but your system now rejects that.
Hope you can help. Otherwise, I still get the automatic updates of musescore.
