I am having basically the same issues. Every few minutes after logging in, the game just freezes completely and I get the Final Fantasy XIV has stopped working message. No error codes or anything. Just freezes up and crashes. I can maybe get 10 minutes of playtime in before it does this, basically making the game unplayable and that is just infuriating. I have tried the typical "fixes" like updating drivers, cleaning cache, etc. but to no avail. Would like to know what's going on and how to fix it. I really enjoy this game and want to be able to actually play it.
