Hi I recently tried a program called FSNight to use darker Night Time Textures but I wanted to go back to the default textures because now I cant see any aircraft parked at the gates at airports. Here is a screenshot at O'hare to show what I mean. What are the names of the Default FS9 textures that this program replaced? I would like to use those instead. Thanks alot for any help. http://forums.avsim.net/user_files/124482.jpg

It would appear that you didn't backup the originals. Your best bet is to re-download the applicable night texture file again and refer to the author's readme.txt and make a list of the files that are affected. Then copy these files from whichever original FS CD is appropriate to your Main Texture Folder which will overwrite the add-on ones.
