Blank ZOHO CRM Screen

I was using the CRM tabs while it was loading it sent me to a black ZOHO CRM page with nothing else on it. I have logged in and out and have tried everything to get back to the home page. As soon as I login that is all that is coming up this is so frustrating as time is being wasted on this ! I need this fixed as soon as possible and of course the help line phone number is closed ! ANYONE PLEASE HELP
