Multiple issues JJSploit

I'm having an issue where its difficult to even get JJSploit to attach in the first place. I have to redownload the files multiple times to even get it to attach. On the off chance that it does attach it will just crash seconds after it does attach. I have done everything I can to try to get it to work (disabling firewall and running as administrator) and it still doesn't work so there really isn't anything I can do differently.
