I'm assuming you're using Windows (then the CygWin envronment). If so, there's a 
hard-coded boundary that limits the number of points to 64.

There are two ways of overcoming this issue:

1) reduce the grid resolution in your GPF (i.e. from 0.375 to 0.4, 0.5...)
2) run the calculation on a Linux/Mac/Unix system (were this limitation doesn't exist).

Hope this helps,
