Turn off your PS3 and start up again, i have had about 3 weird errors on cod4 like things about maps and also something about exceeding 128bones, all weird stuff, yeah just restart, if it keeps happening, try deleting the patch and then re-installing it, if that fails you might need to master reset your ps2, if that fails, then your ps3 has a fault or the cd has a fault. hope i helped.
