AI Aircraft don't show up after a FS9 re-install

Hi Folks I recently had to re-install my FS9 to get rid of a minor problem. The new installation went flawlessly until it came to putting my AI Aircraft back in using TTools. I re-installed TTools as well so that I would get a fresh start. I placed my aircraft and Flight plan info into TTools Aircraft and Flight Plan folders respectively and Compiled Everything with no errors. I then placed all my aircraft folders back into FS9'S Aircraft folder where they used to be. I fired up FS9 only to find Default aircraft and no AI aircraft. I've redone this several times trying to find a solution but still no luck. Most of my aircraft are set for between 25% and 50%. The ATC in the game is set for 100% so that's not the problem. Do any of you have any suggestions? Thanks Ken
