musescores publishing

So.. like when I tried to publish a score named "Ganvairs burden" things didn't go so well and I couldn't post it and after that, the following prompt I got was.
"Your score could not be published
musescore.com returned an error code:401 authorization required.
Please try again later, or get help for this problem on Musescore.com"
does anyone have any solutions for this, it would help everyone and me.
