Cannot open GRD files anymore (DIVA genrated the associated bmp file but can open it)

Dear all,

I’m using DIVA-GIS on a Windows XP and suddenly I was unable to open any raster file (GRD). A pop windows displays an error telling me that the associated bmp files cannot be open. This file is created by DIVA-GIS tough and can be displayed in any other image editors.

I uninstalled and reinstalled DIVA-GIS several times but this problem occurs on every version I tried from 5.2 to 7.3.0.
I'm still able to oead Shepefiles and MrSID.

I suspect the problem may be caused by a program (virus or other GIS application) that changed some low level DLL but I’m still unable to repair my system.

Did any of you ever face this issue before?
