JJSploit doesn't attach to Roblox even though it says it's injected properly.

Hello. JJSploit, an exploit I've just downloaded doesn't want to attach to Roblox even though I'm pressing both "Attach" and "Attach Unsafe" repeatedly. Before this, the exploit was having DLL errors, so I installed the application with the needed DLLs. Can someone tell me whats going on?
