I just recently got my hands on the game and I have been able to play it without the patch, but that just seems to suck not being able to use it. Here is the error I get: "Please remove disc from current CD/DVD drive and insert the original disc in another drive ?:." Has anyone seen this issue before? ------------------ System Information ------------------ Time of this report: 8/31/2008, 17:01:56 Machine name: MATTS-PC Operating System: Windows Vista
