Our system periodically checks for EULA violations (https://www.xogo.io/eula) or accounts with past due invoices. If you are seeing this message on one or more of your screens you may have multiple free accounts which is not allowed by our EULA, or you might need to update the credit card information for your pro account. 
To resolve, just log into admin.xogo.io and make sure your credit card is up to date. If your business is running on multiple free accounts, you would need to delete all but one of your free accounts (log into each one at admin.xogo.io and delete). Then add all of your XOGO players to a single XOGO account.  The XOGO Manager app will prompt you to upgrade to a pro account by adding your credit card info.
