Difficultly importing GeoTiff format


I downloaded Earth data from here. It is a GeoTiff file, which is a map of solar radiation falling on earth.

enter image description here

Mathematica claims to import GeoTiff files. However, when I import,

SetDirectory[NotebookDirectory[]] files = FileNames["*", "./diffuse/"][[1]] diffuse = Import[files, {"GeoTIFF", "Image"}] 

The output is an error:

LinkObject::linkd: Unable to communicate with closed link LinkObject['/Applications/Mathematica.app/Contents/SystemFiles/Converters/Binaries/MacOSX-x86-64/GDAL.exe',6300,8]. Import::fmterr: Cannot import data as GeoTIFF format. 

I can get the file to open using other GeoTiff programs such as QCIS. So it does seem to be a Mathematica issue. Any ideas? It is an error which I have not encountered before.
