sims 2 ultimate collection

[kelsieb101]

Ok, so I had sims 2 downloaded before and it worked perfect, it never asked me to sign into origin when I was offline, I could always play without internet, then I tried to download sims 3, and afterwards it wouldn't let me play without internet, so I tried factory resetting my computer, and just downloading sims 2 again, and now it still says I need internet to play, why is it doing this? And how can I play without internet, I don't have internet at home, and I can't keep walking to the library everytime I want to play sims 2, PLEASE HELP MEEE!!!!!!
