To SimGurus or whom it may concern, I hope you can help me resolve this/these issue(s). I have Sims Medieval, which has been one of my absolute favorite Sims games to play. I was never really able to play with the newer update, so I've stuck with the first version. I've also had the problem of not being able to build the Merchant's Market and play as a merchant, unless I build it first. I have the problem of the game stop working after a few hours too, so I have to start the game again (this particular one I have with the Sims 4 as well, unless I'm online).
However, here's the most significant issue I'm having. I've waited so long to get the Pirates & Nobles Adventure Pack (about five years, I believe), because either I didn't have the money to get it or I couldn't find it in stores and sometimes online. I finally got it yesterday and installed it today. I had to update the base game, and now it won't play at all. I've gone back to the launcher and clicked play, but a message popped up saying the action cannot be done because the game is already running (and to quit the game and try again). I'm at a loss, and I really want to play it. Please help, and thank you for taking the time to read this and look into it.
