Technic launcher not launching anything

[Leiriad]

Hi,  I offered an access to Minecraft to my best friend. I installed it on her computer, and then installed the Technic Launcher, to allow her to join me on my aotbt server. I was asked to run Java, so I downloaded a 64bit of Java 7. It worked fine, and I was able to get AOTBT and vanilla easily. But when I clicked on play, nothing happened. Well, I say "nothing", but it was like the technic launcher disapearing for the Mojang screen, but Mojang never shows, and we're back to the launcher. I tried to uninstall it, delete the .technic file, restart the computer, install again, change java version, allow Java and Minecraft in the firewall, but it does this everytime. I attached the log. Can you tell me what's wrong ?
