Can't use this to predict.

[NinelieAimer]

I'm sorry to bother you, I can't use your package to predict the results.
I can use this package to predict arma(4,0)-grach(1,1), but when I bulid arma(4,0)-grach(1,2) there is something wrong, please help me, I'm really in a hurry.

I use the example code and got the following error:
