The Sims 2: NightLife

Make an image from your origional copy of the game(s) using Alcohol 120%

After that, mount the image to Daemon-Tools v.4.03, install the game, then run the installer for SafeDisc Blocker, it will ask you to point to the game folder your wanting to install for, then choose the exe that needs to be started (speed.exe for NFS) Then run the shortcut that SafeDisc Blocker makes. A box will popup, and load the game, leave it running, after you have finished playing and the game has ended it will tell you to press enter, it wil then put back the registry entries it had removed (ones that get detected by protections such as SafeDisc 4.)

okay i tell you what...

i had same problem..
so all you have to do is TWO steps
but first be sure that you have the mini-images files

step one: - Ummount (University)
[Right Click] on daemon tools trey icon
-> [Virtual CD/DVD-ROM] -> [Device X: University] -> Unmount Image


step two: - Mount (Nightlife)
[Right Click] on daemon tools trey icon
-> [Virtual CD/DVD-ROM] -> [Mount Image] -> [Mini image file]


thats it..

NOTE: my current Daemon tools version is (3.47)
