I can attach JJSploit into game, but I can't execute the script.

Hello everyone, I would be appreciate if you guys answer the question. I used JJSploit to play Roblox Bedwars for fun, and I am currently using window 7. However, I can attach it into the game, with no crash, but after I pasted the script, I couldn't execute it. Previously, I used the same method to attach and execute into the game, and nothing happens, but this time, I couldn't execute. Please help me, thank you very much.
