Recently just downloaded Technic launcher, Was going to play attack of the b team but it didnt launch either then decided on Hexxit and it wont launch alongside tekkit etc.
I have two logs and i will provide both, at first i didnt have enough RAM so i fixed that and still wont launch.. my current situation is not being able to launch any form of modded minecraft from any launcher.. only able to use vanilla.
First file under logs...

Looks like its just repeating itself.. I have not been able to launch any of the games at all so hopefully the logs say something other than repeating
