I honestly have no idea whats happening. It was working one day and now its not and i have done almost everything simple to fix it. Past the basics of uninstalling and reinstalling the client, disabling Java and reactivating it, updating to 8, and restarting my computer i have no idea how to fix this. I see some people posting with like file content to recieve help and I don't know how to do that. I'd love some guidance in fixing this issue. The main problem as far as what the client is doing is: I'll press play it shows all the content loading then the client disappears for a split second and reappears as if I didn't click anything in the first place. PLZ HELP
