Hi i had this problem on my laptop with this game last year if you have vista and only 1gb of ram on your laptop the game will lock up and freeze this is because the windows vista system needs at least all the 1gb of ram you have to run it i put the game on our main quad core vista desktop pc which has 4gb of ram and it runs fine but that is because it also has a top spec graphics card as well as 4gb of ram my relative has it on his pc laptop and he has a core2 duo processor with 2 gb of ram it runs very good on his as well the key factor is ram and a graphics card hope this helps
