Is that a fix to Vexorian's JH or to Cohadar's? I see he hasn't updated it in 1 year but have u updated your NewGen on the site?
Why I'm looking into this right now is because I get my PC back in a couple of weeks and want to install NewGen again so I can resume modding again and maybe even start moderating again if I can re-learn enough stuff.
edit: ok I found where you have JNGP on your site again:

Do you know about Win8 compatibility? I could never get JNGP to install on Win8. If it won't work, I'll just install it on my old Win7 laptop which I'll also get back in a couple weeks.
