AI packs are different from AI planes. Are you sure you followed the installing instruction to the letter?
Try eventually AI packages from another source, if the ones you installed seems not to work (but always be attentive not to install two times the same airline, hairy things may happen if you do

)
You didn't write which packages you installed, so use Google to track either or both Project AI's and World of AI's homepages (Google takes on their pages immediately, no need for me to append URL's). They're freeware.

To learn how to define your own AI traffic, and eventually use in it even a flyable plane, download TTools
here (it's the first on the top) and READ AND LEARN the readme. It's very clear and complete, though long and not particularly simple to put in use. But if I of all people learned how to do it, then everyone can.

I warned you. If you use a flyable and your frame rate drop to nil, I wont take responsibility.

There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
