It is an intel GMA X3100 though?
Well, if you look at the linked page it says that the issue is because nVidia drivers didn't work in 256 colors. Neither did Intel's. nVidia's drivers got fixed; Intel's didn't. But supposedly Starcraft 2 now runs in Thousands of Colors so if that were the problem then it should be fixed. So you could try switching to Thousands of Colors mode (from Millions) and see if that lets it run, but you'll need to provide more details than that if you want better help.
