I have the same problem but with a PC.
@alliegleek there is a patch for the pc (patch 1.69) only. Once you install Origin and get Origin to activate TS3 in Origin you do not need the disc. There is data that is burned to the optical disc in a way that is called over burning. Most optical drives can should read the data but can't write the data thus you can't reproduce the disc. Some optical drives (some manufacturers) will not read the data at all or stop reading it at any time. Replacing the drive usually cures the problem. The alternative is to use Origin. All my TS3 games are disc and Origin automatically added them to Origin and now at version 1.69 I don't need a disc because of Origin. Also this patch lifts the SecuROM install limit.
