Trial CRM Plus -> CRM Professional

Trial CRM Plus -> CRM Professional

Hi everybody.

I`m using Zoho since last week and still have 7 days on my trial mode. I've tested Free, Standard, Professional, Enterprise and finally CRM Plus.

I think the best one for me will be CRM Professional.

From Free to Enterprise, I was swithing between versions in the Setup Menu. Now that i've switched to CRM Plus and i can't go back.

Can someone help me on how to go back to Professional?

Thanks a lot!
