http://scratch.mit.edu/ fails to open for me to upload my problem set 0 for the past 4 days. I had been able to access it before & even registered. It fails on my smart phone & other browser on my laptop and no firewall is on as far as I know. No answer on searches I've made have helped to resolve this.

What do I do?

  • Just open the scratch website on the browser that it works on. It wouldn't work on a smartphone because smartphones don't have the capability to run what Scratch needs. Apr 10, 2015 at 17:29

  • Thanks for your answer but like I mentioned, I had tried on other browsers on my laptop and even 2 days ago logged into the cs50 appliance and tried navigating to the site but same failed result. I have submitted my pset1 however and will continue to try. Thanks again.
