Dear all,  
I have the PyGMT 0.5.0 under conda enviorement over MS Windows10.

```
PyGMT information:
  version: v0.5.0

```

I downloaded the grid files (earth\_relief\_data) from the GMT mirror server. I tried to plot with the following script

cbba = [-67.0000, -64.3555, -18.2500, -16.5500]  
grilla = r’D:\Inves\Pdoc\places\earth\_relief\_02m.grd’  
dgrid = pygmt.grdgradient(grid=grilla, radiance=[290, 85])  
pygmt.makecpt(cmap=“gray”, series=[-1.5, 0.2, 0.01])  
fig.grdimage(grid=dgrid, projection=“M4i”, region=cbba,  
cmap=True)

but I have the following error:

```
Traceback (most recent call last):

    status = c_call_module(

OSError: exception: access violation reading 0x0000021A9298AB94

```

happens the same with all \*grd data that I downloaded from GMT mirrors.  
Does anyone have the same issues?

Stay safe and best regards
