Civil 3D Settings Errors

Hello All,

Is there anybody there who can help me solving this problem below.

Everytime I open Autocad the message below appears, it affected the default settings on Autocad ie. Fill; highlight; mbuttonpan and many more, if I change back the settings manually it's fine, but everytime I open another session it goes back to same problem. I've tried to remove and re-install my software, but problem still the occurs.

Please assist.

Thanks

Rhandy
