I purchased Star wars the best of PC on the 25/12/2010 (Last christmas) so that i could play Star wars knights of the old republic. I have a windows XP computer and i have a C: Drive and a D: Drive ... When i put the disk into my computer, the little CD symbol comes up and then nothing happens. I go to my computer and it says there is nothing in my drive. I managed to get star wars battlefront working for a few minutes but it was super laggy so i closed it and tried it again and it said there was nothing in my drive. Can someone please help me.
