Problem with DKIM setting

Problem with DKIM setting

I purchase my domain from namecheap.com and i followed all the steps on this page 
https://www.namecheap.com/support/knowledgebase/article.aspx/9758/2208/how-to-set-up-zoho-email-for-my-domain

But i keep getting this message:

The DKIM entries are not configured to match with Zoho for the following domain:  woonova.com

it has been more than 2 hours, so i guess something not right. 

Anyone can help?
