CrossFire freezing when watching replays

I like watching certain Search & Destroy replays to see if people are hack.ing

But when watching the replay in first person view (F1), and the person kills someone on the other team using a knife, the program freezes and I am forced to close down.

RIGHT BEFORE THE KILL REGISTERS (using knife, in first person view) is when it freezes.

It ONLY freezes in FIRST PERSON VIEW (F1), and ONLY when someone is using a KNIFE and kills an opponent on the other team.

If the person uses ANY OTHER WEAPON it DOES NOT FREEZE. Pistol, sniper, regular guns, etc., all register and the replay keeps playing.

There is nothing wrong with my install and all my patches update and all other gameplay is fine.

This is a technical issue.

Thanks!
