Jon,
It seems correct now. Thank You, While awaiting your response I also bought Orbx Spain, can you tell me if the below is the correct order. I did put the Spain airports above these entries.
SCENERY_PACK Custom Scenery/Orbx_B_EU_Spain_South_TE_Custom/
SCENERY_PACK Custom Scenery/Orbx_C_EU_Spain_South_TE_Default/
SCENERY_PACK Custom Scenery/Orbx_D_EU_Spain_South_TE_Overlay/
SCENERY_PACK Custom Scenery/Orbx_E_EU_Spain_South_TE_Orthos/
I am rather certain from looking at the order of the others that the Custom, Overlay and orthos is correct just unsure of the Default as I don't see that on the other Orbx TE that I have.
