javascritp=death

hi all, I´ve got a blog at studio23.antville.org where I tried to add some new javascript on my mainpage - but I seem to have forgot to close the script.... now when I try to view my log all I get is a blank page - I can´t access the "edit skins" - function to undo whatever I have done...and skins/save does not work either. that basically means my blog is dead for now... PLEASE HELP!!!!!!!!!!!!!
