Hi Havealot,

There are a number of ways to set up cfsmap, but just to see your island (assuming you are using just using standard cfs textures) save your .bgl file to your main/cfs/scenery and go to the location you created it at.
If you want it to show up in your airport list you will need to create a specific scenery folder and install in the normal way.

Hope this helps
