The was previously installed but i had a typical windows crash, unrelated to the game. Long story short. Had to reinstall windows. I downloaded Sins II again and tried to play it.
So the games is located on my F drive. F:\EpicGames\SinsII....The only thing I have on my C drive is windows and some personal files, it is only 250gb so there isn't a lot of room. So all my games are located on my F drive. .
When it did work, was it on C:\?
That being said, there is nothing game related In C:\Users\insert name\.
That path Yarlan asked about was:
C:\Users\[username]\AppData\Local\sins2 (replace username with whatever yours is)
