Cannot open Zoho Docs on imac

Hi, 

Has anyone got any cures for a problem where Zoho docs wont event open!.  I have reinstalled, rebooted and still no luck.

I now get a message as follows:

  • You can’t open the application “Zoho Docs” because it is not responding.
Any help or advice would be welcome.  

Kind thanks
Michael.
