CD Authentication problems are for the publisher to sort out, it's them that wanted the stupid protection on in the first place!

As for the 'Security Module' issue it's usually down to some Virtual Drive, CD/DVD Emulator or blacklisted software running. Try SR7Stop and Starforce Nightmare instead to disable your CD/DVD drives. If you are mounting in Daemon Tools 4 then SR7Stop won't work so just try disabling your CD/DVD drives in Starforce Nightmare after mounting the image in Daemon Tools.
Multiplayer, did you copy over the cracked
EngineServer.dll from the 1.02 crack? Not sure if this is 100% working though for online, even using a legit CD KEY.
