Dark Ground at Bristol

Hi
Here is a mystery I have just installed and activated succesfully Bristol Xtreme in FS9 everything is working except the ground area and all scenery within it is very dark, time of day is set at 12.30hrs and scenery outside the area of the installed field is normal and in bright sunshine. I do have Flight 1 FS Global 2008 and Ultimate Terrain Europe installed in FS9 now Gary's Bristol has installed on the number 1 spot at the top in the scenery list, could that be the problem?
I had this set up combination working on my old computer but I have now changed to a Vista Home Premium and I am in the process of installing all my Flight Programs, everything is working so I have a feeling it is perhaps the stacking of the scenery files? has anyone come across this problem?

Sorry everybody, the problem was I did not have the Render to Texture selected on the Hardware Tab in Settings, if anybody gets this problem look there first,
