I tried launching into Material Energy 4 today and the launcher crashed back to the desktop. I remembered that I needed to update java, which I did and tried again, but again it crashed to desktop. I've even tried other packs, like Resurrection, and they're also causing the launcher to crash. The error log for the Material Energy crash is http://paste.feed-the-beast.com/view/0af4e846 These all used to work perfectly just a few weeks ago, and I'd really like to figure out what's wrong so I can play again.
