Troubleshooting
❓ Calculate prompts for license▼
Free plan needs sign-in first — go to "License" tab → "Sign in via Website"
❓ license.dat import shows 'Unknown error'▼
Make sure you're on V5.5+ — V5.4 doesn't support admin-key-2026. Download the latest from the website
❓ STEP file analysis fails▼
Check file opens in another CAD app — sometimes files corrupt. Re-export from CAD
❓ AI slow or unresponsive▼
Gemini quota may be exhausted — system auto-fallbacks to OpenRouter. If still down, check internet
❓ Excel Export fails▼
Target file may be open in Excel — close it then re-export
