Usage Limit error although no records added so far

Usage Limit error although no records added so far

So far, I have a simple dummy form that lets a user log in. The form is not linked to a table. When a user logs in, however, and the submit button is clicked, I add a record into another table, specifying who logged in and at what time.

It seems simple and reasonable so far.

However, when I run it, I get this error:

Error details:

Error occured while executing on click script.

Usage limit reached. Your limit is 0. Your current count is 0. Please purchase Add ons or delete some records

I don't have any records within zohocreator. It's a brand new app and other than tables and views, there is nothing in there. Does anyone know why I'm getting this error and how I can fix it?
