Problem with F3 racing with more than 6 AI

[Fabri]

As title say, my crash (better say stop working) come if I have a race in any circuit, and set more then 6 AI with F3 cars. Ì have deleted the folder F3 cars and have done a game check by steam. Not resolved my problem. If I start the race with few cars, 4 or 5, the program go ahead and one time in box I can add more AI cars. Please can someone confirm this bug?
