Well, my guess is that u burned it wrong. First, download the file again. then make sure u read some documents on HOW to burn it CORRECTLY. Once you do that, follow the guide, step-by-step. The burn at 1X speed, sumtimes this helps.
If this all still doesn't work, my guess it that your laser is having a hard time readin the cds. Try calibrating your laser. Dont ask me how as I have no idea, ask sumone who know, I am sure sumone here has done it a few times. All I know is that it's pretty simple.
