Technic won't launch

[DevilStuff]

So technic was working pretty fine and all up to a few hours ago when I downloaded java 64 bit. All of a sudden, the technic launcher wouldn't start. The logo doesn't even appear. Any help would be appreciated, thanks!

I am having the same issue. It used to work, now nothing. MC was having ram issues so I downloaded 64 bit despite already having it, it said I only had 32, so I could increase ram. Now it doesn't even work.
