I have UK2000 Airports Volume 1. Are there any conflicts?
If you own Earth Simulations Isles of Scilly scenery then yes there is a conflict. It is very important that you use the UK2000 configuration tool to inhibit St Mary's airport or else you will have both the ES version and the UK 2000 version active at the same time. The UK2000 version is not compatible with the ES Isles of Scilly base layers.
