I have not used SeaClear for a few years.
Just reloaded and used my KAP file.
All worked perfectly.
Place the KAP file in a folder named Charts
Run MapCal_2.exe > Tools >Autoload List > Scan for New Charts > OK > File > Exit
Run SeaClear_2.exe > File > Chart > List All - there it is. (-:
Here is my chart - NZ56 - 1MB - unzip first: http://www.mediafire.com/?x8adj575i0n5t44
PS I now use OpenCPN with my charts on the notebook. A nice program.
