Zoho Reports Upgrade

I've recently completed the Zoho analytic reports trial and want to keep on using them as part of my subscription. But theirs no way off adding it! All i get is this message:

"You have been downgraded to Free Edition of Zoho Reports. Please upgrade to "standard" or higher edition of Zoho Reports to continue the integration."

When I go to Reports, click on Analytics, there is no zoho reports option to upgrade with! Why do you make it hard to updgrade?
