No Valid License Found - this is a different error. This means NATS can not find ANY license at all for the product, and the entire software is disabled. This usually happens when someone either changes hardware with no warning (as the license is hardware locked), screws up the license file, or tries to circumvent the license in some way. Any program with this error should contact us immediately.
