Critical Warning: You cannot download full versions of WoodWOP or Campus software from random torrent sites or "free download" repositories. Holzher protects its IP aggressively. Illegal copies often contain malware that can brick a $150,000 CNC machine.

| "Invalid Machine ID" | You downloaded the wrong WoodWOP version (e.g., Weeke version on a Holzher machine). Re-download the correct variant from Campus. |
