New user "pending"

New user "pending"

Hello
I created a new user on my Zoho CRMPlus account.
I paid a license for an additional user.
In "Admin panel" I see my new user written in red "Pending".
When I click on "Re-send invitation" I will write a message with "error".
No activation email has been received on the new user's email address.
What to do ?
