mp c6004 security level 2 not printing

[digicor]

on security level 0 prints but gets email knocked off im assuming from no security certs, or what ever, i always use level 2 and dont have any issues, this particular time the machine wont print in level 2, i have been through the level 2 parameters cant seem to find a problem, does anyone know why this wont print in level 2? i have level 0 and certification on right now, but it takes an hour or so for the intrernet police to knock it off... never had level 2 not print...
Thank for any insight
