Problem Installing Application from Marketplace

Problem Installing Application from Marketplace

Hi All,
 
I have a trial account going and am trying to install an application from the marketplace, but it's not installing when I click the install app button. Any Ideas?
 
The application is Contact Manager
https://creator.zoho.com/public/showAppInfo?canvasurl=zkyvdppbg&refererUrl=%2Fplatform%2Fpublic%2Fsearch%3FappName%3Dcontact%2Bmanager%26category%3D-1%26limit%3D10%26count%3D3&refererText=Back%20to%20Search%20Results
 
There is no error generated and it appears to install properly and I get a message saying it has installed successfully, but it never shows up on my home screen.
 
Thanks,
Lost in Zoho
Mark
