Problem solved ! It came from shaders that I added myself in the game, now ot functions perfectly ! Thanks for your answer

No, the problem is that even the HUD doesn't appear, and that's why I don't think the problem comes from the hotkey, as I tried with three different keys.

Hi,

I've got a problem whit that fantastic program when I try my plays on Battlefield 3. The recording seems to be blocked, it seems to be impossible to launch it. The HUD doesn't appear, and I can't record.
Do you know why ?

Thanks in advance, and sorry for my bad english
