Technic won't launch games

[EvanAWolf]

So, Technic launcher is not able to launch any games for me. Whenever I click play the launcher closes and then opens again without the game having been opened. I have it set to hide the launcher, and when it's set to close the launcher on launch the launcher closes but no launch of the game. This is happening with blightfall, attack of the b team, hexxit and tekkit and none of them work. 

I'm not sure what all you need, I copied what was in the console and put it into pastebin though. Any help would be much appreciated.

You are using Java 10. Forge will not work with Java 9 or 10. Install java 8 instead, and make sure it is used under Launcher Options -> Java Settings.
