Okay, I read everything everyone posted and thought to myself, why not just use the no-cd crack AND thesmall image file TOGETHER??? So, I downloaded the 5.5mb no cd crack, deamon tools, and "Sims2-Playdisk-Rip" (whatever file). I installed daemon tools, rebooted, and mounted the sims2 file. Next, I simply replaced the exe with the crack and the game booted up perfectly. I started a game in pleastantville and built a house with NO PROBLEMS!!! I was placeing furniture and the likes and the game did NOT crash at all. I went into another home, and added stuff there, and the game played without a problem and with NO CD! Give that a shot, for it SHOULD clear up all this B.S. I've been reading over and over and over and over and over again. If this doesn't work for you, seriously, you have issues!
Enjoy!!!
