5. Troubleshooting Common Issues

• Charts not displaying: Ensure you have "Vector Charts" enabled in the display options. Use the "Chart Groups" feature if you have multiple chart types overlapping.
• Missing Libraries: On Linux or macOS, reading proprietary formats like CM93 sometimes requires installing extra system libraries (like libarchive).
• Corrupt Files: If OpenCPN crashes when loading charts, the database file might be corrupt. Delete the chart folder from OpenCPN options, restart the program, and add the folder again.

• Primary Navigation: Official, updated, licensed charts (whether raster or vector) from a recognized hydrographic office.
• CM93 v2 Role: Route sketching, familiarization, or cross-referencing on a secondary display. Or for non-critical simulation and training.
