mobile app problems

mobile app problems

I have tried to configure (and pay a subscription for one of my users) zoho app on a Sony tablet and mobile phone. At first it would not configure. Then it did. but now I have been sent a message:

Your 15 days trial account for Zoho CRM's Plug-in for Microsoft Outlook has expired. To continue using the Plug-in, please follow the instructions given below.

And now it does not appear.

Any suggestions??

Cheers

Andrew
