zero process in madgraph

Did you use the default dynamical factorization scale?
This one implements a cut below 4 GeV^2
Since your process seem at quite low energy this might be the issue.

Otherwise your model is not part of our database (which includes all FR public models)
So I can not comment that much.

Cheers,
