It does not mean the software is broken; it means the physical smart card is missing, unreadable, or invalid. Recovery requires hardware inspection, driver repair, or component replacement. License mode is a degraded state allowing only diagnostic reads. | | License Mode | Fallback mode –
The message indicates that the software failed to detect a physical (a cryptographic dongle or SIM-sized card) that holds the user’s paid license. Upon this failure, the software automatically reverts to “license mode” — typically a limited, read‑only, or trial mode with severely restricted functionality (e.g., only detecting the phone, no write operations).
