FEM WorkBench - Can not open Material Dialog

[JamesMarine]

I am a new starter of FreeCAD, when i tried to work out my first case on FEM workbench, the below error when clicking "Solid Material" occured. Does anyone have some suggestion regarding what happened?

File "C:\Program Files\FreeCAD 0.18\Mod\Material\Material.py", line 65, in importFCMat
Config.read(fileName)
File "C:\Program Files\FreeCAD 0.18\bin\lib\configparser.py", line 697, in read
self._read(fp, filename)
File "C:\Program Files\FreeCAD 0.18\bin\lib\configparser.py", line 1015, in _read
for lineno, line in enumerate(fp, start=1):
<class 'UnicodeDecodeError'>: 'gbk' codec can't decode byte 0x93 in position 586: illegal multibyte sequence
