Game error

Ok, I keep getting the same error trying to run Battlefield 1942, Battlefield Vietnam, or Halo: The instructions at "0x0172d6b2" referenced memmory at "0x44892430" The memory could not be read.
WTF is wrong? And before you say "buy the real thing" I have the BF disks sitting right next to me.

- be sure you have latest version of directx installed (in before lol directx, etc.)
- be sure you have latest video drivers
- be sure you don't have an issue with program permissions (i.e., run in administrator mode)
- look in your task manager and see if there is any processes that could be interfering with your game
- reinstall game
- give more information; what are you doing in the game before it occurrs
