I installed Ultimate traffic about 1 week ago, but i had to uninstall/reinstall flight simulator because of some sound error that made corrupt sound come out when i changed view, i uninstalled and it stuffed windows up for some reason, i had to do a repair, i then reinstalled flight simulator and ultimate traffic plus some addon scenery for klax and some australian scenery, when i loaded up the game i got this (view attachment), any help would be great

i've had this problem...i installed some water textures ver 15 by pete wilding and they caused exactly what your seeing..i replaced them with another version and the problem disappeared.does any of your addon scenery mess with the default textures??? if so this could be the problem good luck steve
