Done Can't launch Infinity

I just installed Infinity trough the MyM Launcher and I get this
It just comes up that in console when I press "Launch..." and the launcher is still there, no game.
What do I do? I've tried re-installing.

 

You say you have re-installed it, but have you done a hard-force update?

If that doesn't work, try deleting the instance folder, and do a fresh install again.

From what I can see, you are missing the Scala libraries, which are required for minecraft to run.

 

I just did hard force update, no luck.
Tried deleting instance folder and fresh install, still no luck

 

Thanks SirWill, that fixed it
