Vechs inferno mines caused my game to close when I started recording

I attempted to record Vechs inferno mines map , which has recorded fine up til now, in which when I hit my record key on my keyboard (F6) my game just slowed down and then closed itself. I even tried recording in another world and it worked. Ive recorded it before so its not like my computer cant handle it. My recording software, by the way, is fraps.
