I messed up :( :(

I was installing some lower res autogen to improve FPS, and because of the size of the textures folder I didn't back it up.. In doing so, it replaced some of the airport building textures.. Those were the only buildings I didnt want to affect.. well that, and regular scenery like empire state building, etc. But anyway I need to get the defualts back, or maybe an upgrade kit, if there are any. but just for airport buildings, and regular scenery I dont mind having autogen lower resulution, I dont even notice it.. exept for the ugly airport buildings.. ewww
