Ok,

Finally got it all sorted.

The MapSource version I downloaded before joining here must have been a corrupted/bad download. Since downloading from a link here on GPS, its working and all sorted.

Many thanks for your Help !!

OK,

Now the Map can be opened and seen on MapSource.

Now I can print the chart in sections, but would like to convert the map to a "S57 ENC" Format Vector map or a BSB4 Format Raster map. To use on another Marine Navigation Tool.
