This problem occured when i first used Kris aiact with ILT modifications. The reason was i haven't installed ILT before applying Kris's aiact.
First install one of the Roster Updates.
Then install ILT.
(If you want WebberF1's 250 sigshots, you have to run the batch file of him in the roster savegame folder).
Finally install the aiact you want.
Good luck
