technic laucnher Technic Launcher not launching modpacks

[avtumnb]

Hi

I used to use technic launcher all the time but i stopped for a while and i came back on a few months ago to use it and it wasn't loading the modpacks. I would download it and click play and the page would disappear for about 10 seconds then come back up and wouldn't start the modpack. I've updated java to the latest version and 64-bit. I've looked this up a lot but god damn i cannot find a solution. Please help! I will include the log below.
