I started a new project and can't seem to get content tweaker to run basic scripts, craft tweaker works fine. but even when I try to run a command from content tweaker it does not work.
Like I say I've only started so only have forge, JEI, craft tweaker and content tweaker installed but can't work out what's wrong.

Any help would be appreciated..
