STOP- STOP just take a deep breath for a moment !! Follow along with me - heres the Real situtation - you've apparently downloaded an aircraft or scenery file that some designer/creator didn't know what he was doing and messed up the effects folder which has now corrupted the rest of your Effects folder setting CFG file.. trust me just got thru going down this road myself last week, took me 3 weeks of digging in every file / folder and studying every single line to find the problem and who was responsible for the damage !!! You don't need to un-install anything,,,,, hopefully , you still have all your FSX Discs - all 3 of them,,,, take all 3 of your FSX Discs, and reinsert them starting with the number 1 Disc,, and when the menu screen pops up, it'll ask you if you want to uninstall or FIX your FSX ,,, click on the little dot / circle that clearly states "FIX",,,, it will prompt you when its done and for the next disc on to number 2 and then #3 and then when your done take the last discs out put them back in their little case so you don't mess them up,,, and reboot your compuer and pull back up Flight Simulator,,, hopefully you'll only have to do this once , but you may have to do it 2 times who knows,,,, FSX will fix itself, and over-write any badd or corrupted files with default files regardless,,,,, I'll bet your water turns up black too with water planes and even your ground dirt is black when your aircraft is off the runway,,,, and your smoke effects are screwed up, all blocky/ square and awful looking too- right

?? do what I told you above - follow the steps !!!! The JetRanger ! 8-) 8-)
