Farenheit 1.1 mini image question

[acal3000]

I hace a question about Farenheit, I recently bought the game, installed the patch 1.1, used the mini image, the tdf file and the tetris meulation thing from this site. But sometimes when I run the game the tool and the mini image fools the protection and enter, but sometimes not (put the classic message "insert fahrenreheit dvd") I have to click 3 or sometimes 4 times s and thw works Why this?
