So I have the sims 4 downloaded onto my computer and was using my sisters account, which she doesn't even use. One day it just logged me out and now I can't log into that account, so I made a new one (this one) and its saying I have to buy it again. Is there anyway to bypass that so that I don't have to buy a game that I already have installed on my computer?

You need to buy it because you do not own it. Apparently your sister found out you were using her account and changed the password so you could not use it any more.
