launch ends with non zero status

I always meet this problem when turn the applgrid on. (my amcfast and applgrid settings are fine and the example on aMCfast website can pass in my computer)

For example, I set the process of "p p > w+ > t j [QCD]" in 5-flavor scheme. The error shows

This error happens again in the p p > z [QCD], and p p > z j [QCD]. and it disappears when I turn the applgrid off in the FixedOrder setting. Is there anyone knowing the good solution to this problem.
