When I try to finish the install with disk 2 (I have the collectors edition) I get the following message "An I/O error occured while installing this file. This is normally caused by bad installation media or a corrupted install file". I am just wondering if this is because of a bad disk or if there is a work around for it? (Where I got the game at is a bit of a distance for me is why I am hesitant to rush out and exchange it). Any help would be appreciated.
