If you look at your error message, you'll notice that the computer is having a problem reading the CD.
Therefore you need to start there.
The most common cause of CD read errors is either a scratched or dirty CD. Start there. Examine the CD. Look for any smudges (greasy finger marks are a common cause). You want to use rubbing alcohol and a soft cloth. Use circular motions to clean it (not up and down). To get the best read, the CD must be completely transparent (see your own reflection like a mirror). Rub gently but be firm.
If its slightly scratched, you need to buy a CD repair kit. (About $20). Make sure you get the type that Spins the CD. Its a good investment, Ive saved lots of CDs this way from becoming coasters. The repair kit will apply a new finish to the CD, which will allow the laser to read it.
If its heavily scratched, you have no choice but to ask Activision for a
replacement.
Tell me if this helps.
