Hi chaps, you can use AITM in FS9/FS2004 but you need to download the "Alpha Preview" of v2 and install it as instructed. It lets you select between FS2002 and 2004.
Given that this version has been kicking around nearly a year, I guess the product isn't going to be developed further. However, this alpha version does what I want it to do fine, but I only use certain specific features. Try it, it isn't a huge download.
