I'm here to help share how you can sign in to your account, @ANAjim56.
Let's run one of the QuickBooks Tool functions to get rid of the error message. This way, you can log back into your account and invoice your customers. Let me show you how.
- Download the QuickBooks Tool hub.
- Open and install the downloaded file.
