I need help in using a no-cd crack
 

ok i used to have the sims 2 but it got stolen and when i first got it i made 2 extra sets of the game becuase my baby brothers love to take them and hide them and try and break them and now that they finaly have broke the original copy i had i only had the other copys and when i made them i dint have a clue on how to burn them correctly but i still used them to store the data and i used winrar so i can extract the files into a folder and now that i have made the folder with all the files i try and start up no cd cracks on it and when i go to run it... it gives me a blank error screen and closes... can someone help me?

Do you mean you had the games installed, then copied the installed game onto a CD/DVD, then copied this all back to your PC? You need to update the registry perhaps?
