| Consequence | Description | |-------------|-------------| | Immediate Loss of Verified Features | In many cases, verified features (e.g., high-speed toolpaths, simulation, or post-processing) may be disabled. You can open a file, but you cannot generate new G-code. | | Inability to Save or Export | Some users report that the software enters a "demo mode" where saving files or exporting to other formats (STEP, IGES, DWG) is blocked. | | No Technical Support | If you contact your reseller or CNC Software with this error on a non-genuine license, they will refuse support and may blacklist your company. | | Legal Liability | Using unverified, non-genuine software in a commercial machine shop is copyright infringement. CNC Software actively pursues audits and lawsuits against companies using cracked Mastercam. Fines can reach hundreds of thousands of dollars. | | Malware Risk | Cracks and patches are a primary vector for ransomware, keyloggers, and cryptocurrency miners. The "patch" you downloaded might also include a backdoor to your manufacturing network. | | Corrupted Toolpaths | Most dangerously, cracked software has been known to produce erroneous toolpaths. A seemingly correct program can drive a tool straight into a vise or workpiece, causing crashes, scrapped parts, or injury. |

Case in point: In 2023, a small job shop in the Midwest ignored this warning for six months. When they finally contacted a reseller, they discovered that their "lifetime license" purchased from an online auction site was a cracked USB dongle. The cost to re-program a scrapped titanium aerospace part: $18,000. The cost of a legitimate Mastercam license: $12,000.
