WRD Injection crashing all games.

EDIT: Kind of working now but I can only turn on like 4 buttons before it stops working. The GUI says up and Roblox continues playing, but the commands no longer work. Help :(

I downloaded JJSploit to test it out, and whenever I inject, it crashes no matter the game. Using Nonsense Diamond, (another exploit thing), Injecting Full Lua works, but injecting WRD does not work on that either. I am unable to inject WRD into any game, thus rendering JJSploit useless.. I have injected WRD into other games about once or twice, but ever since then it has always crashed. I'll attempt re-installing ROBLOX again, but in the mean time I am relying on you guys. Thanks :>
