D:GravityRose Online 3DDATATERRAINO_Range.TBL file open error

I am the administrator of my computer. Nevertheless I am getting the following message saying:
D:GravityRose Online
3DDATATERRAINO_Range.TBL file open error

I have made several attempts like to restart to get rid of this. But nothing worked. What should be done now?
Any suggestion?
Please.
