A toshiba satellite is a laptop if i remember very well. And they use onboard graphic cards which may not support OpenGL or Pixel Shading perhaps required from the game.
Im assuming your talking about Dark Messiah of Might and Magic, which requires the following.
AMD Athlon/Intel PIV 3ghz, 1gb Memory, 256mb DX9 Video Card 7gb HDD Space DX9 Compliant Soundcard.
So as you see you need a dedicated Graphic Card. Unless you can give me your Toshiba Satellite model number I can check to see if the onboard card will be compatible.
To make it easier ill add this
