Basically when I place it in, it goes to the autorun icon, but when I press play, it stops, it doesn't even load, also when I go into the cd-rom to try and get it to play, it uninstalls the original and then it gets about halfway into installing the expansion when it says "error". I then have to reinstall the whole game over, also, what are specs, I am not that good at computers? I have a toshiba laptop.
