I'm having a problem where I can't load any new mod packs and several ones I've already had don't work anymore. My Java is Java 7 update 51 but I didn't start having the problem until the newest build, 393, that came out today. I have windows 7 and I'm currently unaware of which bit type of java I have but I'm install both 32 and 64 bit. I have AV. And no Relevant Knowledge progam installed. I fixed it, I uninstalled the mod pack I had that wasn't working and reinstalled it.
