Hello, my dvd rom wouldn't open so I took another one and put it in. That does open and in My Computer sometimes reader as a dvd r and sometimes cd rom. My game exe for Empire Total War and other games shows up the icon that looks like a blank flag and when clicked messages something like this is not a win32 file or I/O error. I tried updating the dvd - a Liteon model - but the message said it wouldn't flash the dvd rom. Help would be appreciated, as ever.
