Don't remove the filters yet. First have him dump the render files and re-render. If that doesn't work, disconnect the clip and reconnect it.
A flat green screen on effects is, as far as I could tell when I encountered them, something to do with Uncompressed 10-bit SD going wonky on a machine that's been upgraded from FCP4.5 to FCP5. I used to have no problems at home, but when I upgraded, kaboom -- this issue started popping up just as with a station at one company I work at. Never happens on DV NTSC projects, either.
