ZOHO Social error - 'permission denied' error code

Hi,
As users of Zoho CRM and Zoho Campaigns, we are keen to trial Zoho Social.  However, when I go to set up a trial, the following error message appears:
error: Permission denied. Please contact administrator, code: 10001
I am using Google Chrome on my PC.  Can you please advise how to resolve this issue.
Many thanks.
