Try setting the delay to 18, then launch the game. If you get an Insert-CD message at that speed then immediately try it again at the same delay (game files will be cached and the game SHOULD launch faster).
If you STILL get Insert-CD then there are probably issues with your game installation or NOCD installation.
Sidenote: By launching with a delay of only 4, you totally override the fix so the crack will perform like the original that I fixed (ie.. crashing when you load a zone). I know, I should have put a low end cap on the delay at 10, but hind sight is always 20/20.
Anyway, hope this helps ya out. If it doesn't my last reccomendation would be to do a reinstall of the game and reapply the v1.05 patch & NOCDfix. All the information on applying it should be in a file called README.TXT. Good luck!
