Overland Panel In FSX

I think I might have posted this question before but never received and answer. I would very much lfike to use Overland's Boeing A/C in FSX and have installed according to last procedures provided from Simmer's Sky (FSX compatible procedure). I have always had a problem with the 747 panel affecting textures at most airports (Terminals and buildings disappear). I have heard of others using these A/C without any problems. Is there some utility that can convert the bitmaps or bmp or whatever into some configuration that would make them acceptable in FSX?Thanks
