The SmarteCD technology can uniquely encrypt and embed an identifying 'black hole' within the content of each individual product CD resulting in technology that can distinguish an original, properly licensed CD from a forgery. With this level of protection, software manufacturers can effectively render forged application CDs unusable.
At the point of CD replication or duplication, SmarteCD physically alters the CD media preventing it from duplication or digital reproduction. Your products become resistant to 'accidental' unauthorized use and professional piracy, as well as preventing unauthorized users from copying CD-ROM content to a hard drive.

a crack enabled your to play the singleplayer campaign but for playing online or LAN you need the original executable (like you said there´s a crc check).
