JJSploit saying Injected but not really injected

I used jjsploit last night and it works but today it no longer works im try to attach it in Survive the Night, it open the cmd tab wher eit says injecting then goes injecting then just closes and nothing happened. I know it would work cause it shows at my bottom right the wearedevs api and stuff but it doesn't show that. is JJsploit working on you?
