Cannot identify cd protection?

[sulphur]

I am currently reading up on this, and am still new. I have tried to identify the cd protection on a game that I own, but I have tried both clonyxxl, and protectionID v5.0b, and both say they cannot identify protection. But Alcohol120 cannot make an image of disk 3, and I have tried a few of the options available, Securom, securomNew, and some others, all to know avail.
I am still reading, and will continue, but any helpful pointers in the right direction for some info would be greatly appreciated
thanks
