Sometimes a laptop doesn't download the version of Direct X need to run diablo 2. Go download the right version of direct X or at least try downloading it again. When you installed diablo 2 did you also use the little thing that they give you to check and see if your pc can run diablo right. If you were to do that it would prob tell you exactly what problem you have and then we can help you from there. If its not the direct X then can you tell me what OS you are running. If it is window vista i don't really know much about it all i know is D2 needs to be run in a different direct x then the newest one out. You can easily fix that by right clicking the icon and changing the settings to run this on.
