First, let me say I am an absolute amatuer when it comes to computers. I'm still learning. Up until last month, I had rarely downloaded anything. Since then, I've had an absolulte blast with this site. However, since last week, the game now plays at a faster speed, no matter I've what set gameplay on. I've tried deleting what I have recently downloaded and it's not working. Should I uninstall the game, wipe everything clean and start from scratch? Thanks.
