CloneCD is not reliable for copying safedisc 2.8+ protected cds.
Use alcohol (which I see that you have) with your Lite-on cdrw to both read and write using safedisc 1 datatype settings.
Only try to run the back-up copy from the drive you used to install the game and, if you play the copy from a writer, make sure that alcohol's Ignore media type is enabled before doing so.
Finally, whilst my recollection is that Splinter Cell is sd 2.8 protected, if your original has sd 2.9 (i.e. mastered later than mine), make sure that CloneCD's virtual drive is not installed on your system and that hide cdr media is not active.
If ccd's virtual drive is installed, uninstall ccd and, if you want ccd on your system, do a custom re-install of ccd without the virtual drive.
Good luck and let us know how you get on.
