I can sign in and log on perfectly fine. I can play for about 5 minutes but then the game will crash and a Hackshield Error pop-up will appear. I don't use mods nor have I ever in the past and I've tried rebooting my computer and restarting the game several times. Is there any reason it's doing this all of a sudden? It was fine a couple days ago but yesterday started crashing. Are there any options for me or do I just have to reinstall?
