Dvd-rom reading some but not new one

Hello,I have the new dvd-rom Sims2 double deluxe.My pc having trouble reading it for installation. No trouble others,for example The Sims, Cultures,Theme Hospital etc. Get message (not responding).Have tried a few times. Once it did read after numerous attempts, and it started to install, but it kept saying could not read certain item it was trying to install. Got as far as 3 % installed and it got stuck on something. I kept hitting 'try again' for over an hour but it couldnt load it. what's the prob and how do I fix it!!!
