Having Trouble When Opening The Website

Hello everyone, I have heard about this music creating site one of my friends. But there is a problem opening the site on my PC. When I try to open this site Notessimo, the site does not open. I dont know why this happens. Could anyone please help?

Try updating your browser, and make sure Javascript is set to allowed. Also try a different browser if that doesn’t work

Thank you for reverting back. I understand why the site was not opening after getting the this guide. I followed some methods from there and the important thing is the antivirus (Avast) was enabled. After disabling the antivirus, the problem got solved. Now I have no problem to open the site.
