The system periodically checks for EULA violations (https://www.xogo.io/eula) or accounts with past due invoices. If you have this message on one or more of your screens you may have multiple free accounts which is not supported by our EULA or you might need to update your credit card information.
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, this is not supported. It will be necessary for your business to either consolidate free players on a single PRO account or upgrade the multiple free accounts to PRO if that is more convenient.
