This injector is not at this site, but at another site. I don't know if I will get into trouble for this, but here goes.
I got tired of all of the injectors here not working for 64-Bit Vista Ultimate. So, I googled "64-bit injector." I found one. See my edit on the bottom for the site. I know it says "Maple Story Hacks" but the injector worked for me, and today is June 8, 2010 for me.
I used Fire Gods latest hack .dll as well.
EDIT: I just checked my url linkup, and it does not work for some reason. Just Google "perx 64 bit injector" and click on the first link that pops up.
