Here's the log :http://pastebin.com/KsmZRxkT I have no idea what any of it means.

I have the same problem and I don't know the right place to ask. I've tried clearing the cache, I've tried re-installing the launcher, and I know I'm using the right recipe for what I'm crafting. I can't find anyone anywhere that's having the same problem. This is the first one I've come across that has the same problem as me and the only answer is not really helpful.
