yes as demi ghost said or you probably installed any other software that alters diablo2 in any way (for example there is a programm to reduce graphics)
my suggestion is re-install diablo2 (or try to replace diablo2.exe and game.exe with the original ones first)
ah may you got a wrong diablo2hackit try this wich is in the sticky for 1.10
if you still got problems ask again
