1. Insert TECDIS service key to enter service mode, and then exit to Windows desktop

2. From the Start Menu go to "All Programs" -> "C-MAP Professional SDK Runtime" -> "C-MAP Chart Manager"

3. Select the "S63-XX" database in the database list (XX meaning database type - 6N or GB)

4. Click "Unregister database" (answer Yes on prompt)

5. Close "C-MAP Chart Manager"

6. Delete the file C:\Program Files\TECDIS\S63SYS\PMT.DAT

7. Then try to load charts on the TECDIS like a normal weekly update.


Please try this first, and if it doesn't solve the issue, I will advise you to contact Telko for further troubleshooting.
