STARGAZER: Error in !class_ind

Hey everyone!
I am having troubles with stargazer in representing graphically the estimation of a model with the pgmm command. The environment tells me:
Error in !class_ind : invalid argument type
I am very surprised for this message, because last night the output was fine and every stargazer command worked properly (I have not changed the code since then). I am not able to detect where the error comes from, is there anyone who has any suggestion about how to fix it?
Thank you in advantage for your help,
Giacomo
