Hi
After downloading the patch, what is your current patch level? Is is updated to 1.67? Do you have any mods or custom content that might be incompatible with the newer patch level?
Look closely at the disc -are there any small scratches, dirt or other damage? Sometimes the game just starts throwing up that annoying message, occasionally because the disc has become damaged, other times just because TS3 is temperamental. Try popping out the disc and reintroducing it to the disc drive a few times. I've had that message a few times in the past and then it would suddenly start working again. Restart your computer before you open the Launcher.
If all else fails you could always register your game codes with Origin and use digital downloads so that the disc is no longer required.
