No ModPacks will launch.

I just downloaded Technic Launcher.  I have Java 64-Bit Version 1.8.0_25.  The launcher fires up just fine, bu when I go to play Attack of the B-Team, it won't even bring up the Mojang start screen and just reverts back to the Launcher.  I've rolled back my Java to 1.7.0_71 and still having the same issue.  Here's the Log, hopefully one of you fine people can help a Minecrafter out.  Thankful for any help.
