''Try'' and other things not working

So all of a sudden ''Try'' has stopped working, most things have. Keystroke wont let me type anything into it. Point and Click does nothing. even if i click ''GO'' it wont go to its coordinates. Load file works fine.
At a bit of a loss tbh!!

Any Ideas?

Thanks.

Have you tried the first troubleshooting step of a Mac reboot?

Hi J!

Yeah, the only thing wrong was "engine not set to load at launch''.

Everything else was a green tick. But still having the problem. Plus the ''GO'' button is not working on the movie and click action.

It's pretty much not working at all!! I've updated and reinstalled it. Everything seems fine in Privacy preferences. Everythings ticked.

At a complete loss!
