Display Textures are wrong

This is an excellent add on . I'm surprised for such a detailed and well documented model for a freeware.
I recently freshly  installed v ersion 5.35 (last installed was so old it crashed the sim when loading). Not it loads ok, but my displays (CAD, CPDS, VEMD) are either blank, or displaying a wrong texture (part of a fire test push button and a fire sign, couldn't attach a screenshot because of the 100 kb limitation). The rest of the display is visible, but has some unintended transparencies (I can't see the exterior through them). I've searched the web and forum and couldn't find anything about this. 
My XP version is 12.4.3-r2.

Thanks.
