The screen to add Tasks, Accounts and Products are not appearing

Hello, there! I'm testing the trial version of Zoho Support for implement here in our company and at the first time we choosed the Express version (which doesn't have accounts, etc). But as soon as we noticed that we will need accounts, we changed (using the proper link at the upper part of the screen) for the Enterprise evaluating version. Now, the button which I need to add the accounts, products and tasks appears, but when I click them, they lead me to a webpage with only the buttons: "Save, Save and New, Cancel" nothing more than the buttons! (look at the attachment)

I have already tried to change the trial plan, and to try other browsers, and to change my language and get back. Nothing worked.

Can you please help-me? I need to choose which support interface we will use here until tomorrow! And if it doesn't work we'll cannot choose Zoho.
