Autodata uses Sentinel SuperPro or UltraPro hardware keys (dongles) or software-based license managers to prevent piracy. When you see the "Sentinel key not found" message, it means the software's security check failed. On Windows 10, this happens because the operating system frequently updates its driver signature enforcement, which disables older, unsigned Sentinel drivers.
