F1 2012 Problem with Flashback

[loma28]

In race,when I do a mistake, I click on Replay, I click F11 to restart the game before crash, but nothing happens. I am in Carreer with McLaren in my second championship, In my first with Toro Rosso it was working properly.
Any suggestion for this problem?
Thank-you

Yesterday in Monaco race I used Flashback and it worked.
So I cannot understand why now it works and than not.
