Suddenly I'm seeing weird black squares in the following situations.1. Upon touchdown the tires show black squares instead of white smoke.2. The propeller effect,i.e. the revolving circle of blades- likewise.3. Black rectangles instead of white waves on the shoreline.The only thing I suspect is newly installed addons that may have affected graphic settings.So here's a list of the last addons I installed (I'm not sure of the order), after which the above problem appeared.GEXUltimate Traffic 2PMDG Beechcraft 1900DHiFi X GraphicsIt's possible that, either one of these is the culprit, or none of them and it's something else entirely.Any ideas?Eytan OrnsteinIntel Core duo E4400 2GHZGeForce 9800 GT4 GB DDR3Windows XP with SP3

Your effects textures are corrupted, do a repair install of FSX.http://www.forum.aerosoft.com/index.php?showtopic=37345
