Sync Crm with Zoho marketing automation.

Sync Crm with Zoho marketing automation.

I have Zoho one. 
When I am in marketing automation, I go in leads, sync and crm is not linked, I do add new account and it says organization is already integrated and on the same it says account not associated.
What is wrong with zoho?
It is sunday evening and I do not want to waste my life trying to connect stubborn apps together. I want a life, fix your sh**t right now.
