Don't use Nero - use
Clone CD with the Game profile.
How do you expect to get "some REAL" help if you didn't give details - your initial plea for help was no more than a sentence and only contained one piece of information.
If you have used the very latest Clony XXL and followed it's instructions (such as it asking is the game installed so it can check for Securom New), and it still shows no protection, then it is likely to contain no protection - maybe just cd checks.
If this is the case then there would be no intential errors on the cd, but the slowdown around 6% may be attibuted to your original cd being scratched. Try Clone CD with it's automatic Fast Error Skip - also change the options so that it shows the read errors it finds as this may help to show what the errors are (intentional or accidental).
Another question - have you actually tried making a copy of it - that is a copy you have burned and tried to play with (not just attempting to read it).
Again - the more detail you go into, the more detailed answer you will receive!!
