I can not make/view any sequences

[amazing333144]

I try placing down notes and nothing happens. I try playing the instruments by pressing on the keys and it toggles the hover color change but i can't click them and it doesn't make a sound. Also all the notes dissapear whenever i try to load or play a sequence and  i hear nothing. It's like there was never anything there. HELP

Make sure your browser is up to date and clear the browser cache. Also OS doesn't really work very well on Safari or Internet Explorer
