Textures missing from Caribbean scenery?

Hi all.I downloaded all of Jimmy Martin's awesome Caribbean scenery and have installed a few so far. The scenery is great and makes my caribbian flights much more enjoyable. Kudos to Jim, Great work!However, I am noticing some object do not have textures, they are just white shapes. This is particularly noticeable in the Caribbean ships scenery and in some of the additional island airport buildings (MYNN comes to mind). I have all the Nova textures installed and have followed his install instructions to the letter. Has anyone else had this problem? Thanks.Doug
