FRAPS in Crysis

Greetings.
It seems that I have already met a similar topic on some forum, but I would like to know why, when I am going to take a screenshot or shoot a video in the first Crysis, using FRAPS, it just shoots me a black screen? In the case of video, the screen is black, and the sound is on the recording. Maybe someone managed to fix this? If so, how?
Thank you for attention.
