Try a clean reinstall of the game. In order to perform a clean install of
the game, you'll need to perform the following procedures.
1) Uninstall the game using the Add/Remove Programs control panel in
Windows.
2) Delete the folder for the game, located on your hard drive. When you
uninstall a game, this folder is usually left behind for you to delete
manually.
3) Restart your computer, and run the programs Scandisk and Disk
Defragmenter. These are two utilities that are provided with Windows, and
they monitor, clean, and repair your hard drive.
4) Disable applications running in the background.
To do this, hold down the CTRL+ALT+DEL keys, all at the same time. This
will bring up the Close Program dialog box. In here, you will see a number
of items. The only ones that Windows needs to run are Systray and Explorer.
All other programs here are extraneous, and are not necessary for Windows to
function.
Since they may be causing conflicts or memory problems, you will want to
turn them off. Don't worry - nothing we do here is permanent; everything
here will return when you restart the computer. Select a program (besides
Explorer and Systray), and then click the End Task button at the bottom of
this window. If another window pops up saying that the program is not
responding, click End Task on this window as well. This will drop you out
to the desktop. Press CTRL+ALT+DEL again, and repeat as necessary until
only Explorer and Systray are left.
5) Clean the CD.
You can do this by washing the CD under luke-warm water. Use a liquid
detergent that is non-abrasive and use your fingers to spread the soap
evenly across the shiny underside. To dry the CD use a soft cotton
lint-free towel that will not create any further scratches. Paper towels
are highly discouraged due to the abrasive nature of the fabric.
When drying, make sure that you wipe from the inner-circle towards the
outer-circle. Wipe against the grain, so you don't leave streaks the same
way that the laser reads.
6) Reinstall the program.
7)Especially make sure you disable your Anti-virus software.
